 After completing an eventful year, ISRO  (http://www.business-standard.com/search?type=news&q=Isro)is gearing up for some satellite launches this year, with the IRNSS 1D  (http://www.business-standard.com/search?type=news&q=Irnss+1d)being the first, which would put in place India's own navigation system on par with the Global Positioning System  (http://www.business-standard.com/search?type=news&q=Global+Positioning+System)of the US.
 
 "The launch campaign for IRNSS 1D has come, which starts on January 16. Within two months, all components from other ISRO labs have to reach Sriharikota. The launch is likely after March 15," a senior ISRO official told PTI.
 
 IRNSS 1D is the fourth in the series of seven satellites, the national space agency is planning to launch to put in place the Indian Regional Navigation Satellite System (IRNSS). While four satellites would be sufficient to start operations of the system, the remaining three satellites would make it more accurate and efficient.
 
 The other launches also relate to the IRNSS series with the IRNSS1E and IRNSS1-F satellites to be launched before the year end, he said.
 
 The first three satellites in the IRNSS series were launched from Sriharikota on July 1, 2013, April 4 and October 16 last year respectively.
 
 The fully deployed IRNSS would consist of three and four satellites in GEO stationary and in inclined geosynchronous orbits respectively, about 36,000 km above the Earth.
 
 The system would provide two types of services -- Standard Positioning Service, which is provided to all the users and Restricted Service, which is an encrypted service provided only to the authorised users.
 
 The IRNSS system was targeted to be completed by this year at a total cost of Rs 1420 crore.
 
 IRNSS is designed to provide accurate position information service to users in the country as well as the region extending up to 1,500 km from its boundary, which is its primary service area.
 
 A sel ect group of countries have their own navigation systems --Russia's Global Orbiting Navigation Satellite System (GLONASS), United States' Global Positioning System (GPS), European Union's Galileo (GNSS), China's BeiDou satellite navigation system and the Quasi-Zenith Satellite System.
 
 ISRO not only launched a GLSV rocket, a GSLV Mk III, besides two PSLVs during 2014 but also successfully ins erted its Mars orbiter in to the Martian atmosphere and tested the re-entry of unmanned crew module fr om space.

ЦитироватьНЬЮ-ДЕЛИ, 7 января. /Корр. ТАСС Александр Антипин/. Индия начала подготовку к запуску четвертого из семи спутников в рамках создания первой собственной региональной навигационной спутниковой системы (Indian Regional Navigation Satellite System, IRNSS), сообщило информационное агентство Пресс Траст оф Индиа.

"В течение двух месяцев на единственный космодром в Индии, расположенный на острове Шрихарикота вблизи южной части побережья штата Андхра-Прадеш, будет доставляться необходимое для запуска оборудование, - сообщил источник агентства в космической области. - Сам запуск (спутника IRNSS-1D) состоится после 15 марта".

Как рассказал ранее в беседе с корр. ТАСС глава Индийской организации космических исследований (ИСРО) Коппиллил Радхакришнан, создание навигационной системы должно завершиться в 2015 году. Пуск первого аппарата (IRNSS-1A) состоялся в июле 2013 года, второго (IRNSS-1B) - в апреле 2014 года, третьего (IRNSS-1C) - в октябре. Все три аппарата вывели на орбиту собственные индийские ракеты- носители серии PSLV.

Как ожидается, система будет покрывать территорию индийского субконтинента и еще около 1,5 тыс. км от его границ. Она предназначена для гражданских и военных целей. Стоимость создания системы оценивается в 14,2 млрд рупий (более 230 млн долларов).

Satellite set for launch
Special Correspondent

IRNSS 1D, a navigation satellite developed by the Indian Space Research Organisation (ISRO), is planned for launch on March 15, said ISRO Satellite Centre Director S.K. Shivakumar.
He said the GPS-Aided Geo Augmented Navigation (GAGAN) system has also become operational. The system is a pioneering effort for the application in aviation sector.
IRNSS 1D is the fourth in the series of seven satellites planned for launch by ISRO for setting in motion the Indian Regional Navigation Satellite System (IRNSS).

Dennis S. Jesudasan

The 59-hour countdown for the launch of IRNSS 1D satellite, which will help India kick-start functioning of indigenous navigation system on a par with the U.S.' Global Positioning System (GPS), will commence at 7.35 am on March 7.

The launch is scheduled at the first launch pad of Satish Dhawan Space Centre at Sriharikota at 6.35 p.m. on March 9, a senior ISRO official told The Hindu .

Fourth satellite

IRNSS 1D is the fourth of the seven satellites to be launched to put in place India's very own satellite navigation system, which will be established at a cost of Rs. 1,400 crore.

Though the launch would help the ISRO commence initial operations on the system, the formal commencement of the IRNSS function would be announced a few months later, as the satellite would have to take its final position.

ЦитироватьThe launch of India's fourth Navigation Satellite IRNSS-1D onboard PSLV-C27 was originally scheduled for March 09, 2015 from Satish Dhawan Space Centre, Sriharikota. During the integrated electrical checks of Launch Vehicle along with Satellite after the closure of heat shield on March 03, 2015, an anomaly was observed in one of the telemetry transmitters of the Satellite. In order to resolve the technical anomaly through further test, simulation and analysis, the launch of PSLV-C27 with IRNSS-1D has been postponed.

ЦитироватьThe Indian space agency plans to launch its fourth regional navigation satellite by March-end after replacing a faulty transmitter, a senior official said on Tuesday.

"We are planning to launch the satellite by the end of this month. The replacement transmitter is getting ready and will be brought from our centre in Bangalore," M.Y.S. Prasad, director, Satish Dhawan Space Centre (SDSC), told IANS on the phone from Sriharikota, around 80 km from Chennai.

ЦитироватьISRO's Polar Satellite Launch Vehicle, PSLV-C27, successfully launched the 1425 kg IRNSS-1D, the fourth satellite in the Indian Regional Navigation Satellite System (IRNSS) today evening (March 28, 2015) from Satish Dhawan Space Centre SHAR, Sriharikota. This is the twenty eighth consecutively successful mission of the PSLV. The 'XL' configuration of PSLV was used for this mission. Previously, the same configuration of the vehicle was successfully used seven times.

After the PSLV-C27 lift-off at 1719 hrs IST from the Second Launch Pad with the ignition of the first stage, the subsequent important flight events, namely, strap-on ignitions and separations, first stage separation, second stage ignition, heat-shield separation, second stage separation, third stage ignition and separation, fourth stage ignition and satellite injection, took place as planned. After a flight of about 19 minutes 25 seconds, IRNSS-1D Satellite was injected to an elliptical orbit  of  282.52 km X 20,644 km (very close to the intended orbit) and successfully separated  from the PSLV fourth stage.

After injection, the solar panels of IRNSS-1D were deployed automatically. ISRO's Master Control Facility (at Hassan, Karnataka) took over the control of the satellite. In the coming days, four orbit manoeuvres will be conducted from Master Control Facility to position the satellite in the Geosynchronous Orbit at 111.75 deg East longitude with 30.5 deg inclination.

IRNSS-1D is the fourth of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS-1A, 1B and 1C, the first three satellites of the constellation, were successfully launched by PSLV on July 02, 2013, April 04, 2014 and October 16, 2014 respectively. All the three satellites are functioning satisfactorily from their designated orbital positions.

IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS would provide two types of services, namely, Standard Positioning Services (SPS) - provided to all users - and Restricted Services (RS), provided to authorised users.

A number of ground stations responsible for the generation and transmission of navigation parameters, satellite control, satellite ranging and monitoring, etc., have been established in many locations
across the country.

In the coming months, the next satellite of this constellation, namely,IRNSS-1E, is scheduled to be launched by PSLV. The entire IRNSS constellation of seven satellites is planned to be completed by 2016.
