IRNSS


IRNSS [ISRO]

The Indian Government has approved in May 2006, a project to implement an Indian Regional Navigation Satellite System (IRNSS) in the next six to seven years. It will consist of a constellation of seven satellites and a large ground segment. Three of the seven satellites in IRNSS constellation will be placed in Geostationary Earth Orbit and four in Geosynchronous Orbits inclined at 29° to the equatorial plane. All the seven satellites will have continuous radio visibility with Indian control stations.

Each satellite has two payloads: a navigation payload and CDMA ranging payload in addition with a laser retro-reflector. The payload generates navigation signals at L5 and S-band. The design of the payload makes the IRNSS system inter-operable and compatible with GPS and Galileo.

India to launch first navigation satellite in June
IANS | Mar 16, 2013, 09.38 PM IST

BANGALORE: India will launch in June the first of the seven Indian Regional Navigation Satellite System (IRNSS) into the earth orbit to provide real-time position, navigation and time services to multiple users, the space agency chief said on Saturday.

"We are preparing to launch the first of the navigation satellites constellation in June to provide position accuracy better than 10 metres over India and the region extending up to 1,500km around the subcontinent," state-run Indian Space Research Organisation ( Isro) chairman K Radhakrishnan told reporters on the margins of a space event here.

The IRNSS-1 will be launched on board the polar satellite launch vehicle ( PSLV-C22) from the spaceport at Sriharikota off the Bay of Bengal on Andhra Pradesh coast, about 90km northeast of Chennai.

The space agency plans to launch the second navigation satellite three months after in-orbit tests of the first one and the remaining five satellites over a 14-month period by 2014-15.

The IRNSS will have a space segment (constellation of satellites and signal-in-space), a ground segment and a user segment to provide multiple services on 24x7 basis under all-weather conditions to a host of users, including airlines, ships and observational posts.

"Three satellites will be placed in the geostationary equatorial orbit (GEO) at 34, 83 and 131.5 degree east and two satellites each in the geosynchronous orbit (GSO) with equator crossing at 55 and 111.5 degree east at an inclination of 29 degree," Radhakrishnan said after inaugurating a two-day symposium on the 'Saga of Indian Remote Sensing Satellite Programme: 25 years since IRS-1A', being held here this weekend.

The navigation system will have two signals in L5 and S-band on 1176.45MHz frequency and 2492.028MHz frequency with provision for downlinks.

"The constellation system provides two basic services — standard positioning service for civilian users and restricted service for authorized users. The navigation software is being indigenously at the satellite centre in Bangalore," Radhakrishnan added.

IRNSS-1 weighs 1,380 kg and is the first of the three satellites that make up the IRNSS series. It will go up on the next PSLV mission, the C-22. "Unlike the PSLV C-20 which was a core-alone version of the launch vehicle, C-22 will be the full version with all six strap-on motors," Ramakrishnan said.

India to launch first navigational satellite on June 12
Last Updated: Friday, May 17, 2013, 18:23

India to launch first navigational satellite on June 12 Bangalore: India proposes to launch its first navigational satellite, which will provide terrestrial, aerial and marine navigation services and help in disaster and fleet management, on June 12.

The Indian Regional Navigation Satellite System-1A is slated to be launched on board home-grown rocket, PSLV-C22 XL at 1.01 am from Sriharikota spaceport on June 12.

The launch window will be open from June 10 to June 15, sources in the Indian Space Research Organisation here said.

The 1425 kg IRNSS-1, which will have a life span of about ten years, will provide satellite-based terrestrial, aerial and marine navigation services, and also help in disaster and fleet management and vehicle tracking, an ISRO official said.

Bangalore-headquartered ISRO has planned to have a constellation of seven satellites under IRNSS by 2014-15.

IRNSS is an independent regional navigation satellite system, and once all the spacecraft become operational, it would provide position accuracy, similar to Global Positioning System (GPS), of better than 10 metres over India and the region extending about 1,500 km around the country.

"It is designed to provide an accurate real time Position, Navigation and Time (PNT) services to users on a variety of platforms with 24x7 service availability under all weather conditions", the official said.

IRNSS provides two basic services -- standard positioning service for common civilian users and restricted service for special authorised users, the official said.

ISRO Navigation Centre Inaugurated

The ISRO Navigation Centre (INC), established at Indian Deep Space Network (IDSN) complex at Byalalu, about 40 km fr om Bangalore, was inaugurated today (May 28, 2013) by Mr. V. Narayanasamy, Minister of State in the Prime Minister's Office, Ministry of Personnel, Public Grievances and Pensions. INC is an important element of the Indian Regional Navigation Satellite System (IRNSS), an independent navigation satellite system being developed by India.

Speaking on the occasion, Mr Narayanasamy appreciated the commitment and dedication of Indian space scientists in realising the objectives of the country's space programme. The Minister also gave away various awards instituted by Astronautical Society of India (ASI) and ISRO.

IRNSS will have a constellation of seven satellites and enables its users to determine their location and time accurately. These satellites will positioned in geostationary and inclined geosynchronous orbits 36,000 km above the earth's surface. IRNSS coverage will extend over India and its neighborhood and the satellites are equipped with high precision atomic clocks and continuously transmit navigation signals to users.

As the focal point of many critical operations of IRNSS, ISRO Navigation Centre is responsible for providing the time reference, generation of navigation messages and monitoring and control of ground facilities including ranging stations of IRNSS. It hosts several key technical facilities for supporting various navigation functions.

Key to the navigation support is the time reference to which all ground systems and the satellite clocks are synchronised. This time reference is generated by the high precision timing facility located at INC. This timing facility is equipped with high stability, high precision atomic clocks to provide stable and continuous time reference to the navigation system.

IRNSS will have a network of twenty one ranging stations geographically distributed primarily across India. They provide data for the orbit determination of IRNSS satellites and monitoring of the navigation signals. The data from the ranging/monitoring stations is sent to the data processing facility at INC wh ere it is processed to generate the navigation messages. The navigation messages are then transmitted from INC to IRNSS satellites through the spacecraft control facility at Hassan/Bhopal. The state of the art data processing and storage facilities at INC enable swift processing of data and support its systematic storage.

INC is connected to the ranging stations and to the satellite control facilities through two highly reliable dedicated communication networks consisting of satellite and terrestrial links. The hub for the satellite communication links is hosted at INC.

Polar Satellite Launch Vehicle (PSLV-C22) flight delayed by a fortnight

IRNSS-1A, the first Indian Navigation Satellite, was scheduled for launch onboard PSLV-C22 on June 12, 2013 at 01:01 hrs. from Satish Dhawan Space Centre, Sriharikota. IRNSS-1A Satellite has gone through all electrical checks and is ready for propellant filling. The PSLV-C22 vehicle was fully integrated and was undergoing electrical checks.

During the electrical checks of the launch vehicle, an anomaly was observed in one of the electro-hydraulic control actuators in the second stage. It has been decided to replace this actuator.

The replacement of the control actuator needs two weeks of activity at the Launch Pad and the Vehicle Assembly Area. Accordingly, the launch of PSLV-C22/IRNSS-1A is delayed by a fortnight with respect to the original scheduled date of June 12, 2013.

June rocket launch delay not to affect ISRO plans
Last Upd ated: Thursday, June 06, 2013, 15:30

Chennai: Even though the June 12 rocket launch has been put off to June-end or the first week of July because of the failure of a component, Indian space agency officials do not expect this se tback to impact other rocket launch plans.

Even the ambitious Mars mission planned in 2013 would not be affected, officials said.

"We have sufficient time between the launches and we are confident of closing 2013 with five launches. One rocket launch (carrying Saral satellite) is already over in February. So, only four remain," said a senior official at the Indian Space Research Organisation (ISRO), seeking anonymity.

ISRO had planned to launch its first regional navigation satellite (IRNSS-1A) on its Polar Satellite Launch Vehicle-XL (PSLV-XL) variant June 12, but had to put it off after finding a problem in one of the electro-hydraulic control actuators in the second stage/engine.

The rocket was fully assembled with the satellite when the problem was detected, during checks.

"The second stage had to be dismantled to replace the actuator which is an assembly of several components. It weighs around 20 kg. We have replaced the component and tests are on," said an ISRO official.

Incidentally, in February 2011, a gas motor in the second stage control actuators did not perform as per expectations and had to be replaced, delaying PSLV's flight carrying Resourcesat-2, an earth observation satellite, and two other payloads, by nearly a month.

However, ISRO officials do not think that there is a problem in the quality of components as one or two in a batch may fail.

The navigational satellite is intended to provide terrestrial, aerial and marine navigation services and help in disaster and fleet management across the region.

Following the PSLV-XL launch, ISRO is planning to launch its communication satellite G-Sat 14 using heavier rocket - Geosynchronous Satellite Launch Vehicle (GSLV) - powered with a domestic cryogenic engine sometime in August, 2013.

Preparatory work for the G-Sat 14 launch is going ahead at the rocket launch pad in Sriharikota in Andhra Pradesh, around 80 km from here.

These two launches will be followed by the mission to Mars later this year. The launch of one more remote sensing satellite is also being planned before the end of the year.

Indian Space Research Organisation has now scheduled the launch of the country's first navigation satellite for July one after rectifying an anomaly. Indian Space Research Organisation has now scheduled the launch of the country's first navigation satellite for July one after rectifying an anomaly.

BANGALORE: Indian Space Research Organisation has now scheduled the launch of the country's first navigation satellite for July one after rectifying an anomaly.

"Review is on. It's scheduled to be launched at 11.43 PM on July one", ISRO sources told PTI here today.
