ЦитироватьGSLV to launch GSAT–14 during mid-2012[/size]
The Indian Space Research Organisation, which has planned to put three satellites into the orbit with its Polar Satellite Launch Vehicle before end of this year, will send its GSAT -14 with its indigenously developed Geosynchronous Satellite Launch Vehicle D-5 during mid-2012, Chairman, ISRO, K. Radhakrishnan has informed.
Speaking to reporters after inaugurating the two-day national conference on 'Expanding frontiers in propulsion technology' at Liquid Propulsion Systems Centre (LPSC) in Mahendragiri in the district on Friday, Dr. Radhakrishnan said the ISRO, which had learnt a lot of highly valuable lessons from the unsuccessful flight of GSLV D-3 in April 2010, was working hard on the rectifying the problems to make the GSLV D-5 flight a resounding victory. GSAT–14 satellite would have C-band communication transponders.
Towards achieving self-reliance in the development of the Mark III engine for GSLV, the S-200 solid propellant motor would be subjected to static test, which would be the repeat of the successful test that was conducted in January 2010.
Moreover, the ISRO has planned to launch GSAT – 12, which will have extended C-band transponders, with its Polar Satellite Launch Vehicle during next month.
After launching Meghatropique satellite, an Indo – French joint venture, in September 2011, the ISRO will be concentrating on the launching of Microwave Remote Sensing Satellite – RISAT – 1 – during December this year.
"Our PSLVs will launch these satellites that will provide us clear and excellent pictures even though the sky is overcast," Dr. Radhakrishnan said.
According to the ISRO chief, his prestigious testing centre at Mahendragiri had been adorned with one more most-modern facility – Thrust Chamber Test Facility – for testing the GSLV Mark III engine's cryogenic stage. "It will be ready for commissioning within next 60 days".
Inaugurating the conference, Dr. Radhakrishnan stressed the need for engaging more private firms with adequate and state-of-the-art research and development facilities in ISRO's missions and the leading educational institutions as is being done in the United States and Russia.
He stressed the need for developing non-chemical, electro and ionic propellants, "which will have longer life and propel the satellite in its orbit for more period."
Releasing the conference proceedings, Sathish Dhawan Space Centre Director M.C. Dathan hoped that the ISRO, with its highly committed and enthusiastic young workforce, would scale greater heights in the days to come.
Vikram Sarabhai Space Centre Director P.S. Veeraraghavan said due importance should be given for developing eco-friendly 'green propellants' and for launching a payload with nuclear fission.
LPSC Director S. Ramakrishnan delivered the keynote address on 'Expanding frontiers in propulsion technology'. Former LPSC director AE. Muthunayagam and Aeronautical Society of India secretary general Ashok Bhushan offered felicitations.

Megha-Tropiques [ISRO]
The french-indian Megha-Tropiques satellite is devoted to the atmospheric research. The data collected by the satellite will allow to improve our knowledge on the water cycle contribution to the climate dynamic in the tropical atmosphere and our understanding of the processes linked to the tropical convection.
The basic principles of the Megha-Tropiques mission are to:
provide simultaneous measurements of several elements of the atmospheric water cycle : water vapour, clouds, condensed water in clouds, precipitation and evaporation,
measure the corresponding radiative budget at the top of the atmosphere,
ensure high temporal sampling in order to characterise the life cycle of the convective system and to obtain significant statistics.
Megha-Tropiques will be built on ISRO's IRS bus instead of the originally planned Proteus Bus to reduce the pressure on CNES budget. The payload is constituted of:
MADRAS : a microwave imager aimed mainly at studying precipitation and clouds properties,
SAPHIR : a 6 channels microwave radiometer for the retrieval of water vapour vertical profiles and horizontal distribution,
SCARAB : a radiometer devoted to the measurement of outgoing radiative fluxes at the top of the atmosphere.
MADRAS is to be developed jointly by ISRO and CNES. SAPHIR and SCARAB are to be developed by CNES.

ISRO getting ready for climate research satellite Megha-Tropiques launch[/size]
BANGALORE: Indian Space Research Organisation has set in motion preparations for launch of Megha-Tropiques, an advanced weather and climate research satellite, on board PSLV from Sriharikota spaceport next month-end.
"Preparations are underway for launch of the satellite in September end", sources in the Bangalore-headquartered space agency told PTI today.
ISRO and French National Space Centre (CNES) signed a Memorandum of Understanding for development and implementation of the joint atmospheric satellite mission nearly seven years ago.
Sources said top CNES officials are slated to witness the launch by PSLV, ISRO's work-horse launch vehicle.
Megha-Tropiques (Megha meaning cloud in Sanskrit and Tropiques meaning tropics in French) is meant for investigating the contribution of the water cycle in the tropical atmosphere to climate dynamics.
The satellite would carry four scientific instruments, including a Microwave Analysis and Detection of Rain and Atmospheric Structures (MADRAS) radiometer developed jointly by ISRO and CNES to provide information on rain above the oceans and integrated water vapour content in the atmosphere.
ISRO has built the Megha-Tropiques spacecraft, which is similar to the Indian Remote Sensing (IRS) satellites.
"The satellite will be placed in 867 km high orbit at an inclination of 20 degrees with respect to the equatorial plane. In this orbit, the satellite will be able to collect scientific data covering the tropical regions", a senior ISRO official said.
Placing it in a low inclination orbit would facilitate high temporal re-visit capability over the tropical region. This orbit would enhance observational capability of the rapidly developing tropical systems and enable monitoring of weather and climate over the entire tropical world.
ISRO would control the satellite in orbit and also receive, process and distribute the scientific data from the satellite.
"Megha-Tropiques is an important mission which will provide vital atmospheric data over the tropical region that would help in monsoon variability studies", the official said.
Megha-Tropiques, with its unique combination of scientific payloads and its special orbit,is expected to provide valuable data for climate research.Besides Indian and French scientists scientists, international teams of scientists working on global climate related studies had evinced keen interest in the Megha-Tropiques mission.
Megha-Tropiques, one of the most advanced and complex tropical weather and climate monitoring satellites, has been conceived primarily to investigate the tropical regions as they receive maximum energy from the Sun than they radiate back into space.[/size]

05 September 2011
Cannes, September 5 2011. Thales Alenia Space has delivered to the Indian Space Research Organization (ISRO) the flight model of the Radio Occultation Sounder for the Atmosphere (ROSA), which will be integrated into the Indian-French Megha-Tropiques mission designed to study our planet's atmosphere. The delivery took place at ISRO's Satellite Centre (ISAC) in Bangalore.
Developed and built under ASI contract, the ROSA instrument is composed of a GPS receiver and two dual frequency antennas to pick up signals through the atmosphere. The instrument conducts its atmospheric sounding by monitoring navigation signals from the satellites of the GPS constellation while – as seen from the observing satellite – they set through the atmospheric limb on the Earth's horizon or raise from it.
Raw data measured by ROSA are beamed back to Earth where the analysis of the phase delay on GPS signals crossing through the troposphere give a wealth of information, from which it is possible to determine the temperature, pressure and humidity of the atmosphere, and thus to issue forecasts on the evolution and motion of weather fronts, to evaluate climatic trends, and to map the electron density as well as irregularities in the ionosphere in order to predict magnetic storms. The radio-occultation method allows to achieve a better vertical resolution than other infrared or microwave sensors.
The ROSA instrument was entirely designed and built by Thales Alenia Space Italy as prime contractor on behalf of ISRO. The instrument to be integrated on Megha-Tropiques will complement a science payload also consisting in three other instruments, one of which was jointly developed by ISRO and CNES (Centre National d'Etudes Spatiales), the French Space Agency, and the other two by CNES alone. This is the third similar sounder to be delivered by Thales Alenia Space. The previous two flight models were launched on September 23, 2009, onboard India's Oceansat 2 satellite for ISRO, and on June 10, 2011, on Argentina's SAC-D (Satelite de Aplicaciones Cientificas) for CONAE (Comisi

BANGALORE: When Isro's Polar Satellite Launch Vehicle blasts off from the Satish Dhawan Space Centre in Sriharikota later this month, the dreams of about 100 students would be realised.
For over three years now, students from the Indian Institute of Technology Kanpur (IITK) and the Chennai-based SRM University have been working on the design and development of two nano satellites.
Jugnu and SRMSAT designed and developed by the IITK and SRM University, respectively, will ride piggy-back on the Indo-French Megha-Tropiques when it will be launched from the spaceport later this month.
Professor Nalinaksh S Vyas, Jugnu project coordinator, told DNA that over 50 students from IITK were currently in Bangalore to give final touches to the satellite. "Final tests and integration are currently on at the ISRO Satellite Centre, Bangalore," he said.
According to the Jugnu team, the programme development started in 2008 with a team of just three students and over time, the team has grown to 50 students drawn from I year undergraduate course to final year postgraduate courses and 14 professors from different disciplines.
The main objectives of the mission are to initiate research activities for the development of MEMS-based Nano-satellite, to test new cheap solutions for the future cost-effective space missions, to set the path for future upgradations and study such validation concepts for possible upgradations.
The SRMSAT is a 10 kg satellite, which has been designed and developed by SRM University's Mechanical, Aerospace, Electrical, and Chemical Engineering students. The satellite will monitor green house gases in the atmosphere.
ISRO has in the past launched student satellites. The space agency had launched STUDSAT, India's first pico-satellite which was developed by a consortium of seven engineering colleges from Karnataka and Andhra Pradesh.
It had also launched the Indo-Russian satellite YOUTHSAT for stellar and atmospheric studies earlier this year.IIT Kanpur students who are part of the project.[/size]

Place: Bangalore | Agency: PTI
India's top space agency today said the launch date of the Indo-French 'Megha-Tropiques' mission to study tropical climate, is slated for October 12.
"October 12th 11 o'clock is our target (for the launch) at the moment," Indian Space Research Organisation (ISRO)
Chairman K Radhakrishnan, who is also Secretary in the Department of Space and Space Commission, told reporters in Bangalore. It will be launched from the Sriharikota spaceport.
Bangalore-headquartered ISRO today held a pre-shipment review of Megha-Tropiques craft, weighing about 1,000kg, that has undergone all ground tests.
Megha-Tropiques (Megha meaning cloud in Sanskrit and Tropiques denoting tropics in French), would be launched by India's workhorse rocket, the Rs90-crore PSLV (C18).
The satellite, with a five year life, will investigate the contribution of water cycle in the tropical atmosphere to climate dynamics.
ISRO has built the Megha-Tropiques spacecraft at a cost of Rs80 crore, along with an "equal contribution" from the French Space Agency CNES, officials said.
PSLV-C18 would also launch three nano satellites -- one from Luxembourg, "Jugnu" research spacecraft from IIT Kanpur and the third one to monitor greenhouse gases from SRM University.
Megha-Tropiques would carry three payloads (two by CNES and one jointly by ISRO and CNES) and a complementary scientific instrument.
"It's quite different from the remote sensing satellite or earth observation satellite that we have built so far," Radhakrishnan said.
"What's unique about this mission is of interest for the entire tropical region. As far as the output of this system (Megha-Tropiques) is concerned, the entire group of climate researchers are going to benefit.
"What we have today is a firm request from US and Europe for using Megha-Tropiques data," he added.[/size]

It will be launched from Sriharikota on October 12; two satellites built by students
Preparations are on for the lift-off of the Polar Satellite Launch Vehicle (PSLV-C18) from the spaceport at Sriharikota at 11 a.m. on October 12.
Global tropical weather
The rocket will put four satellites in the orbit: Megha-Tropiques, built by India and France to understand global tropical weather and climate; SRM Sat, built by the students of SRM University, near Chennai; Jugnu, a satellite integrated by students of the Indian Institute of Technology (IIT), Kanpur; and VesselSat from Luxembourg.
The information sent by the instruments on board the Megha-Tropiques will help understand the behaviour of Indian monsoons and occurrence of cyclones, floods and droughts.
Heat shield
The PSLV has been fully integrated, said K. Radhakrishnan, Chairman, Indian Space Research Organisation (ISRO), on Tuesday from Bangalore. "The Megha-Tropiques and the three co-passenger satellites have been fully integrated with the vehicle. The heat-shield was closed last morning." The heat-shield around the satellites protects them from the intense heat during the launch and the vehicle's ascent into the atmosphere. After the rocket reaches a certain altitude, the heat-shield falls off.
Dr. Radhakrishnan said the final checks were under way. "On October 8, we will have a launch rehearsal. The vehicle readiness review will take place on October 9 followed by the Launch Authorisation Board meeting the same day itself. As of now, the launch is scheduled on October 12 at 11 a.m."
The PSLV-C18 — which will be the 20th PSLV to be launched — is the core-alone version of the four-stage PSLV, without the strap-on booster motors that will put the four satellites in orbit.
Megha-Tropiques (Megha in Sanskrit means cloud and Tropiques in French is tropics) is one of the most advanced and complex satellites built to monitor the weather in the short-term and climate in the long-term in the tropical regions of the world. It is a joint project of ISRO and the French space agency, Centre National d'Etudes Spatiales (CNES).
Thermal engine
ISRO officials said the 1,000-kg satellite had been built to investigate the tropical regions which received the maximum energy from the sun than they radiated back into space.
The excess energy received in the tropical region is used as a thermal engine and provides circulation in the atmosphere and the oceans.
'Life cycle'
"The complex processes between solar radiation, water vapour, clouds, humidity, precipitation and atmospheric motion determine the life-cycle of convective systems and influence the Indian monsoon in the tropical region," the ISRO officials explained.
From its perch in the sky at an altitude of 867 km, the Megha-Tropiques would help study, on a sustained basis, the rapidly developing weather systems in the entire tropical world. Thus, the information beamed by the Megha-Tropiques will be useful not only to India but to all the countries in the Indian Ocean region and other parts of the world.
Scientific payloads
The satellite has four scientific payloads. The Microwave Analysis and Detection of Rain and Atmospheric Structures (MADRAS), built by ISRO and the CNES, will provide an estimation of rainfall, water vapour, liquid water, ice and surface wind. Scanner for Radiative Budget (SCARAB) will study the radiation received by the earth and reflected by it. The third instrument, Sondeur Atmospherique du Profil d'humidite Intertropicale par Radiometrie (SAPHIR) will investigate the humidity present in the tropical atmosphere.
The CNES has built the SCARAB and the SAPHIR. The GPS-ROS (Global Positioning System- Radio Occultation System) from Italy will study the temperature and humidity at different altitudes.
The ISRO Satellite Centre, Bangalore, integrated the entire satellite.
The 10-kg SRM Satwill help in understanding global warming and pollution by studying carbon-dioxide and carbon-monoxide present in the atmosphere. The three-kg Jugnu has a camera to take pictures of the earth to monitor, vegetation, reservoirs, lakes, and ponds. VesselSat will help in locating the ships in the sea-lanes of the world.[/size]

Sriharikota readies for rocket blast-off[/size]
indianexpress Express News Service , The New Indian Express
CHENNAI: India is priming to fire into orbit Oct 12 a satellite designed to help study climatic and atmospheric changes in the tropics, the country's space agency said Thursday.
"The rocket and its payload have been assembled and the heat shield has been closed. The first round of tests are over and we will have a final review. The launch rehearsal will be on Oct 8," an official of Indian Space Research Organisation (ISRO) told IANS.
Preparations are in full swing at Sriharikota, the rocket launch site in Tamil Nadu around 80 km from Chennai, and Indian space scientists say they are confident they will be able to fill the ferrying vessel with propellant Oct 10.
The official, who did not want to be identified, said the Polar Satellite Launch Vehicle (PSLV) will ferry the 1,000-kg Megha Tropique and three smaller satellites together weighing 45 kg.
Megha Tropiques is an Indo-French collaboration to study climatic and atmospheric changes in tropical regions and will make India the second nation in the world to launch such a space mission.
The Tropical Rainfall Measuring Mission (TRMM) -- a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA) designed to monitor and study tropical rainfall -- was launched Nov 27, 1997.
According to Indian space officials, ISRO will bear the launch cost of around Rs.90 crore while French space agency Centre National d'

Countdown for launch of PSLV-C18 starts[/size]
CHENNAI: The 50-hour countdown for the launch of Indo-French climate monitoring satellite Megha-Tropiques and three other nano satellites on board PSLV-C18 on October 12 from the spaceport of Sriharikota is progressing well, the ISRO said.
"The countdown for the launch started at 9 AM today. The countdown will be for 50 hours. All the mandatory checks will be made in PSLV-C18, before the launch. The launch is scheduled at 11 AM on October 12," ISRO spokesman S Sathish told PTI.
Megha-Tropiques will carry three payloads - two by France's space agency CNES and one jointly by ISRO and CNES - and a complementary scientific instrument.
ISRO has built Megha-Tropiques, an advanced tropical climate monitoring satellite, at a cost of Rs 80 crore with "equal contribution" from French government space agency, Centre National d'Etudes Spatiales.
Megha-Tropiques (Megha meaning cloud in Sanskrit and Tropiques denoting tropics in French) will investigate the contribution of water cycle in the tropical atmosphere to climate dynamics.
The other three nano satellites are one each from Luxembourg, the indigenous 'Jugnu' of IIT-Kanpur and SRM University, Chennai.
Data received from 'Jugnu' will be studied with a tracking system installed at IIT-Kanpur and pictures and information received from it will be used for research.
Jugnu will also help gather information on floods, drought and disaster management.
This will be the fourth ISRO mission this year, including one launched from French Guyana.[/size]

As the PSLV-C18 carrying Megha-Tropiques, an Indo-French venture to study the atmosphere in the tropical regions, blasts off from Satish Dhawan Space Centre at Sriharikota on October 12, students will be holding their breath at the ground station at SRM University in the city outskirts.
Along with Megha-Tropiques, SRMSAT, a nano-satellite, to monitor the green house gases, carbon-dioxide and water vapour in the tropics using a grating spectrometer will be launched.
"Fifty students were involved in design and development of SRMSAT, one of the first nano-satellites to be launched by a private university in the country," said P. Sathyanarayanan, president, SRM University.
"There is a dedicated lab at the university. All the students involved in the project worked at the lab, after college hours, for the past two years, choosing to stay late in the night designing and testing each and every instrument," says L.B. Vishal, a mechanical engineering student.
When they found that the power amplifier on board was dissipating heat, the students came up with heat sinks. Likewise, communication systems were arrived at after a lot of simulation. Students of 12 departments began work on the satellite with the survey of literature and Loganathan, a former ISRO scientist and product architect of space systems at the university, was available 24x7 to make the dream project a reality. ISRO scientists conducted a review of the project every month and gave insights.
Of cuboid model, the nano-satellite weighs 10.4 kg with three solar panels and was made at a cost of Rs.1.5 crore. The grating spectrometer will monitor earth-based sources and sinks of green house gases for the next two years.
Already in place, the ground station consists of two Yagi-Uda antennae with low noise amplifiers and Trans-receiver and auto tracking is through a satellite tracking programme. "The ground station has been tested by tracking the existing satellites," says D. Narayana Rao, Director, Research.
"The University is in talks with ISRO to start a Centre for Space Sciences in its Chennai campus. It will take six months to crystallize," Mr. Sathyanarayanan said. University Chancellor T.R. Pachamuthu and Vice-Chancellor M. Ponnavaikko were present.[/size]

SRM all set to launch satellite[/size]
CHENNAI: SRM University will become the first university on Wednesday to launch a nano-satellite and the first private university to launch a satellite of its own. The satellite called SRMSAT, when launched, will also be the only satellite monitoring the Green House Gas emissions in the region, according to university authorities.
"The satellite will conduct a real-time integrated column measurement of the Green House Gases and will have a ground station at the university campus that will be monitored by the students," said Narayan Rao, Director of Research and Development. The satellite will also be tracked by the ISRO tracking service from the first week of its launch. "The data collected by the satellite will be used for non-profit scientific purposes," Rao added.
The nano-satellite, which was planned about two years ago, had 52 students working on its research and development in collaboration with experts from the Indian Space Research Organisation (ISRO). It was built at a cost of `1.5 crore. Students with Electronics and Communication, Electrical Engineering, IT and Computer Science backgrounds worked on this project. "Students had taken leave and permission from their respective institutions to get involved in the project," said P Satyanarayana, Vice-Chancellor, SRM University.
SRMSAT was transported to Sriharikota last Saturday and the launch authorisation board has approved its launch along with the Indo-French satellite Megha Tropiques on Wednesday. "Following this launch, we will get into the development of SRMSAT-2 in the next two years," said Chancellor TR Pachamuthu. The university is also in talks with the ISRO to set up a centre for space technology on its campus.
The university, according to its Chancellor, has set up a separate team for research on space technology and has obtained grants worth `20 crore for research activities. "We are regularly visiting and interacting with foreign universities such as

A weather sentinel to peer over the tropics[/size]
The data provided by the Megha-Tropiques atmospheric research satellite will help provide insights into the patterns of rainfall in the world's tropical regions.
After a difficult and, at times, uncertain gestation lasting over a decade, the Indo-French atmospheric research satellite, Megha-Tropiques, is at last ready to leave aboard the Polar Satellite Launch Vehicle (PSLV), from Sriharikota.
Prior to the two countries joining hands in this effort, scientists in both countries, along with their respective space agencies, had been independently considering similar sorts of missions. In the late 1980s and the early 1990s, the French were examining the possibilities for a 'Tropiques' satellite. The Indians, for their part, were thinking of a 'Climatsat' satellite around the mid-1990s.
The idea of merging these efforts came about as a result of contacts between scientists in the two countries.
In 1998, the space agencies, the Indian Space Research Organisation (ISRO) and the Centre National d'

PSLV launches Megha-Tropiques atmospheric research satellite for IndiaЦитироватьIndia's Polar Satellite Launch Vehicle has made its twentieth launch Wednesday morning, carrying the Megha-Tropiques atmospheric research satellite and three other spacecraft into orbit. Liftoff from the Satish Dhawan Space Centre was on schedule at 05:30 UTC (11:00 local time).
Indian Mission:
Megha-Tropiques is a one-tonne satellite which will be operated as part of a joint programme between the Indian Space Research Organisation (ISRO) and France's Centre National d'Etudes Spaciales (CNES). The spacecraft was constructed by ISRO, based around the IRS bus developed for earlier Indian satellites, and carries four instruments which will be used to study the Earth's atmosphere.
The primary instrument aboard Megha-Tropiques is Microwave Analysis and Detection of Rain and Atmospheric Systems (MADRAS), a microwave imagery payload which was jointly constructed by ISRO and CNES.
Using a conical scanning radiometer rotating at a rate of 25 revolutions per minute to scan the Earth's surface, it provides nine channels for imagery at five different frequencies, with both horizontal and vertical polarisation at all frequencies except on the M2 channel.
The M1 channels are at a frequency of 18.7 gigahertz to study precipitation over oceans. The M2 channel has a frequency of 23.8 gigahertz, with only vertical polarisation, and will be used to study water vapour. M3 has a frequency of 36.5 gigahertz, and will be used to study precipitation over seas, and water in clouds.
M4, with a frequency of 89 gigahertz, will monitor convection in areas of rain, whilst M5 will use a frequency of 157 gigahertz to search for ice within clouds. Channels M1 to M3 have spatial resolutions of 40 kilometres, whilst M4 has a resolution of 10 kilometres, and M5 has a resolution of 6 kilometres.

Индия вывела в космос аппарат для исследования муссоновЦитироватьНЬЮ-ДЕЛИ, 12 окт - РИА Новости, Евгений Пахомов. Индийская ракета-носитель PSLV-C18 вывела в среду в космос четыре спутника, в том числе совместный индийско-французский космический аппарат для исследования муссонов, сообщает информационное агентство IANS.
По данным агентства, индийская ракета-носитель PSLV-C18 (Polar Satellite Launch Vehicle) благополучно стартовала утром в среду с космодрома Шрихарикота, который расположен на одноименном острове в Бенгальском заливе. Ракета вывела на орбиту спутник Megha-Tropiques, разработанный совместно специалистами Индии и Франции.
Этот аппарат, который весит около тонны, предназначен для исследования процессов развития и движения муссонов в тропической зоне, а также для изучения влияния глобального потепления на муссоны, отмечает индийская пресса.
Ракета также вывела на орбиту еще три небольших спутника, в том числе аппарат, созданный студентами расположенного в Ченнаи Университета Шри Рамасвами и спутник, разработанный специалистами Индийского технологического института в Канпуре.
Индия выступает активным игроком на мировом рынке коммерческих запусков спутников. Как ранее сообщили прессе представители Индийской организации космических исследований (ИСРО), эта организация намерена в ближайшие два года вывести на орбиту 12 иностранных спутников. За последние 10 лет Индия уже отправила в космос 26 спутников по заказу различных стран, включая Германию, Израиль, Южную Корею и Сингапур.

T.S. Subramanian
Along with Indo-French satellite Megha-Tropiques, PSLV-C18 rocket on Wednesday successfully placed in orbit three nano satellites —— VesselSat1-1 from Luxembourg, SRMSat from SRM University, Chennai, and Jugnu from IIT, Kanpur
India's Polar Satellite Launch Vehicle (PSLV-C18) demonstrated its reliability once again when it put successfully four satellites in orbit on Wednesday. The satellites were: Megha-Tropiques, an Indo-French satellite to study the weather and climate in the tropical region of the world; SRMSat built by the students of SRM university, near Chennai; Jugnu, built by the students of the Indian Institute of Technology (IIT), Kanpur; and Vesselsat from Luxembourg. This was the 19th consecutively successful mission of the PSLV out of 20 launches from 1993.
It was a flawless a mission with the PSLV-C18 rising from the first launch pad at the spaceport at Sriharikota at the scheduled time of 11 a.m. As the vehicle sped up from the launch pad, it disappeared briefly into the clouds to knife out into the sky again. Applause broke out in the Mission Control Centre as the four stages of the vehicle ignited on time and fell into the Bay of Bengal. At the end of more than 21 minutes of flight, the PSLV-C18 first catapulted the 1,000 kg Megha-Tropiques satellite into a precise orbit at an altitude of 867 km. The satellite was slung into orbit at a velocity of more than 26,000 km an hour. A few seconds later, SRMSat flew out, followed by VesselSat and Jugnu.
Consistency
K. Radhakrishnan, chairman, Indian Space Research Organistion (ISRO) called it "a grand success". P.S. Veeraraghavan, Director, Vikram Sarabhai Space Centre, Thiruvananthapuram, said the latest success demonstrated the consistency of the PSLV rocket. S. Ramakrishnan, Director, Liquid Propulsion Systems Centre, ISRO, described the flight as "one more magnificent mission from the PSLV."
Dr. G. Raju, project Director, Megha-Tropiques, said the satellite's solar-panels had deployed and the satellite was in good health. The satellite would have a life-span of five years. T.K. Alex, Director, ISRO Satellite Centre, Bangalore, said that even though SRMSat and Jugnu were small satellites, they were complex spacecraft built by the students.
Predicting the monsoon
Megha-Tropiques, with four scientific instruments, will help in predicting the Indian monsoons, floods, cyclones and droughts, besides estimating the weather in the short-term and climate in the long-term in the tropical countries of the world. The 11-kg SRMSat will address the problem of global-warming and the pollution levels in the atmosphere by monitoring the carbon-dioxide present there. The 3-kg Jugnu isa remote-sensing satellite that will minor vegetation and water-bodies. VesselSat will help in locating ships cruising in the sea-lanes of the world.

Successful launch of PSLV-C18 / MEGHA-TROPIQUES Mission[/size]
India's Polar Satellite Launch Vehicle (PSLV-C18) successfully launched the Indo-French MEGHA-TROPIQUES Satellite on October 12, 2011. This has been the nineteenth successive successful flight of PSLV.
Three co-passenger Satellites (a) JUGNU from IIT, Kanpur (b) SRMSat from SRM University, Chennai and (c) VesselSat-1 from Luxembourg were also launched by PSLV-C18. The user institutions also have confirmed establishing contact with the satellites.
MEGHA-TROPIQUES Satellite, a joint endeavour of ISRO and the French National Space Agency (CNES), is intended to study the water cycle and energy exchanges in the tropical region covering 20 deg on either side of the Equator.
There are four Science instruments in the MEGHA-TROPIQUES Satellite:
A Scanning Microwave Imager MADRAS (developed jointly by ISRO and CNES), operating at five frequencies (18, 23, 37, 89 and 157 Giga Hertz) to measure precipitation and cloud properties
A Scanner ScaRaB (developed by CNES), for measuring Earth Radiation Budget
A Sounder SAPHIR (developed by CNES) for Atmospheric Profiling of Humidity in the inter-tropical Region
GPS Radio Occultation Sensor ROSA (procured by ISRO from Italy)
Soon after separation of the MEGHA-TROPIQUES satellite from PSLV, ISRO's Telemetry Tracking and Command Network (ISTRAC), Bangalore took its command and control.
It has been confirmed that the Satellite has been placed very precisely into its intended circular orbit, as given below:
Orbital Parameter at Satellite injection Point.....Target.........Achieved
Perigee (km).....................................................865.30+20......864.39
Apogee (km).....................................................867.15+20......865.16
Orbital Inclination (degree).................................20.06+0.20.....19.99
MEGHA-TROPIQUES Satellite has been put in its final orbital configuration in 3-axis stabilised mode with respect to Sun and Earth. The Satellite is in good health. The four Science instruments were energised in the following manner:
ROSA payload was switched on October 12, 2011
SAPHIR payload was switched on the forenoon of October 13, 2011
MADRAS payload was switched on the afternoon of October 13, 2011
ScaRaB payload was activated on October 13, 2011; however for degassing, it is required to wait for 21 days before the collection of data
Data from these instruments is expected to enhance scientific knowledge in the field of climate research through study of water cycle and energy exchanges in the tropical region. Other than the scientific community of India and France, there are already 21 scientific teams from Australia, Brazil, Italy, Japan, Korea, Niger, Sweden, UK and USA awaiting data from MEGHA-TROPIQUES.
It is pertinent to note that MEGHA-TROPIQUES is only the second mission of this kind globally, next to the Tropical Rainfall Measurement Mission (TRMM) launched in 1997 by USA and Japan. USA and Japan are presently coordinating for establishing a Global Precipitation Measurement Mission with 8-Satellite Constellation.
MEGHA-TROPIQUES Satellite could be a joint contribution from India and France to the global scientific community engaged in research on climate and weather systems that affect the daily life of humankind world over and particularly in the tropical region.[/size]

07 марта 2023
"Последние два импульса торможения, примерно по 20 минут каждый, были выполнены в 16:32 и 18:22, соответственно, путем запуска четырех двигателей тягой 11 Н на борту спутника. Окончательный перигей был оценен менее чем в 80 км, что указывает на то, что спутник войдет в более плотные слои атмосферы Земли и впоследствии разрушится. Анализ аэротермического потока при входе в атмосферу подтвердил, что крупных фрагментов обломков не осталось», — сообщил представитель ISRO.
...
ISRO постепенно снижала перигей спутника (ближайшую точку к Земле) с августа 2022 года, выполнив серию из 20 маневров и израсходовав около 120 кг топлива. Многочисленные маневры, включая окончательную стратегию торможения, были разработаны с учетом нескольких ограничений, включая видимость траектории входа для наземных станций, место падения обломков в пределах заданной зоны и допустимые режимы работы подсистем, в частности максимальную развиваемую тягу и максимальное ограничение по продолжительности работы двигателей.
«Все планы маневрирования были проверены, чтобы гарантировать, что ни один из маневров не приведет к опасному сближению с другими космическими объектами, в первую очередь с пилотируемыми космическими станциями, такими как МКС и Китайская космическая станция», — сообщил представитель ISRO.
...
Последние телеметрические данные подтвердили, что спутник вошел в атмосферу Земли и должен был разрушиться над Тихим океаном, окончательный предполагаемый регион падения находится в отдаленном районе Тихого океана в пределах ожидаемых границ по широте и долготе.
...
В последние годы ISRO предприняла активные действия для повышения уровня соответствия признанным на международном уровне руководящим принципам по предупреждению образования космического мусора. По словам представителя ISRO, предпринимаются усилия по созданию собственных средств отслеживания и мониторинга космических объектов для защиты индийских космических активов.
