Re: RISAT 1A and RISAT 3 to be Launched

Iirc IRNSS will be a constellation of 7 satellites, however it's a regional system, wont cover the entire earth.

IRNSS is the first Phase.

Re: RISAT 1A and RISAT 3 to be Launched

It all depends on the sucess/failure of the GSLV MkIII mission...

Our entire space industry depends on the success of the GSLV program. The more the failures, the more the delays.

Communication-Centric Intelligence Satellite (CCI-Sat) - Indian Space Projects


Communication-Centric Intelligence Satellite (CCI-Sat)

The satellite is being developed with a budget of Rs 100 crore by theDefense Electronics Research Laboratory (DLRL) under the Defense Research and Development Organization (DRDO).

The existence of the project was revealed on Tuesday, February 2010 by DLRL director G. Bhoopathy.

"We are in the process of designing and developing a spacecraft fitted with an intelligent sensor that will pick up conversations and communications across the borders," he told reporters in Bangalore before the start of the first international conference on electronic warfare (EWCI 2010).

The satellite will feature a Synthetic Aperture Radar (SAR) and be used for imaging and communication. It will be capable of detecting conversations and espionage activities in the region.

"The satellite will orbit Earth at 500 km. and cover hostile regions in the area by passing on surveillance data to intelligence agencies," G. Bhoopathy, DRDL director told AW&ST in November 2010.

The satellite will be launched in the lower earth orbit — about 500 km above the earth — on board the polar satellite launch vehicle (PSLV).

The satellite, which will be operational by 2014, will also serve as a test bed for anti-satellite weapon development.

With C band spot beams we can have highly encrypted communication even for our hand held military devices hopefully will be integrated in our F INSAS program and the 6 meter high gain antenna of S band will give us lossless transmission of our Mil comm data packets all over the country and in our neighboring countries.
Proud of you ISRO now we need longer antennas in the future and more SAR satellites too.

GSAT-6 military satellite put in its orbital slot




The Indian space agency on Sunday said it had successfully positioned the country's military communication satellite GSAT-6 in its orbital slot.

According to Indian Space Research Organisation (ISRO), GSAT 6 has been successfully positioned in its orbital slot of 83 degrees East and co-located with INSAT 4A, GSAT 12, GAAT 10 and IRNSS1C on Sunday morning, after carrying out four drift arresting manoeuvres.

The satellite was launched by India's heavy rocket geosynchronous satellite launch vehicle-Mark II (GSLV) and put into geo transfer orbit (GTO) on August 27.

One of the advanced features of GSAT-6 satellite is its antenna - the largest satellite antenna realised by ISRO and utilised for five spot beams over the Indian mainland, which exploit the frequency reuse scheme to increase frequency spectrum utilisation efficiency.

The satellite provides communication through five spot beams in S-band and a national beam in C-band for strategic users.

The satellite's life expectancy is nine years.

ISRO is planning to launch 2,200 kg INSAT-3DR meteorological satellite next July with its GSLV rocket.

According to ISRO, with two back-to-back successful missions carrying indigenous cryogenic stage, the GSLV has matured into a reliable launch vehicle and has paved the way for its future operational missions, providing India self-sufficiency in launching higher capacity satellites into geosynchronous transfer orbit (GTO).

The 2016 July launch would be followed by the GSAT-9 satellite launch in May 2017.

The prestigious Chandrayaan-2 Mission is designated to be launched by GSLV in 2017-18 time frame.

According to ISRO, the GSLV is well on its way towards international and commercial operations.

Work is already in progress on the joint effort with NASA for the launch of NISAR satellite into a polar orbit by 2020-21. This mission will demonstrate the versatility of the GSLV for launch into various orbits.

While technical criticalities of the complex GSLV system have been overcome, challenges are being taken up for improving the payload capability from the present 2,117 kg to the design target of 2500 kg, ISRO said.

Detailed studies are in progress, addressing the various ways of achieving this target, said the Indian space agency.

Hostile neighbours push India, Israel to forge space ties



The heads of the Israel Space Agency (ISA) and the Indian Space Research Organisation (ISRO) met this week in Bengaluru to draw up a roadmap of cooperation in this high technology sector. If all goes well early in 2017 two Israeli Nano-satellites will also be launched from Sriharikota.

Avi Blasberger, director general of the Israel Space Agency (ISA), confirmed that one key area of cooperation being explored is "remote sensing using microwaves".

This is essentially a technology where special birds called RadarSats are deployed that have the built in capability of day and night surveillance and these eyes in the skies can even see through overcast cloudy skies, giving the enemy little room to hide.
