    India is expected to have its own satellite navigation system, with the launch of three more satellites before the end of this year, said the Indian space agency's chief on Monday.
    Indian Space Research Organisation (ISRO) chairman K.Radhakrishnan told IANS that Indian communication satellite INSAT-3E has been decommissioned couple of days ago and the users are being migrated to other satellites.

    "We will be receiving the signals from our navigation satellite system by the end of this year. We will be launching three more navigational satellites before the end of this year," Radhakrishnan said over phone from Bangalore.

    The ISRO will be launching the second navigational satellite badged Indian Regional Navigation Satellite System-1B (IRNSS-1B) April 4 evening at 5.14 p.m.

    The 1,432 kg satellite will be carried by Indian rocket Polar Satellite Launch Vehicle (PSLV).

    According to Radhakrishnan, though the IRNSS is a seven satellite system, it could be made operational with four satellites.

    The two more navigation satellites will be launched during the second half of 2014.

    Prior to that, ISRO will be launching the French satellite SPOT-7 and four other foreign satellites in a PSLV rocket and also test its heavier rocket - the Geosynchronous Satellite Launch Vehicle (GSLV) Mark III version, said Radhakrishnan.


    The IRNSS-1B satellite with a design life span of 10 years will be part of the seven-satellite Indian regional navigational system. The first navigational satellite IRNSS-1A was launched in July 2013.

    The navigational system, developed by India, is designed to provide accurate position information service to users within the country and up to 1,500 km from the nation's boundary line.

    The system is similar to the global positioning system of the US, Glonass of Russia, Galileo of Europe, China's Beidou or the Japanese Quasi Zenith Satellite System.

    The system will be used for terrestrial, aerial and marine navigation, disaster management, vehicle tracking and fleet management, integration with mobile phones, mapping and geodetic data capture and others.

    While the ISRO is silent on the navigation system's strategic application, it is clear that the IRNSS will be used for defence purposes as well.

    According to the ISRO, the IRNSS-IB has been realised within seven months of the launch of the IRNSS-1A.

    Satish Dhawan Space Centre (SDSC)-SHAR director M.Y.S.Prasad told IANS: "Even if a navigation system has more than four satellites, the final precise data is picked from four satellites."

    Meanwhile Indian space agency officials are getting ready for the 58.5 hour launch countdown slated to begin April 2 around 6.45 a.m.

    "Normally 53 hour countdown is sufficient. But we have decided to an extended countdown so that some break time could be given for the officials," Prasad said.

    On the issue of INSAT-3E satellite, Radhakrishnan said the satellite was launched in 2003 and its lifespan has come to an end.

    "Users are being migrated to other satellites," he said.

    How good or bad is our navigation system compared to the ones already functional?

    More or less equal,Main point is it will be useful for spying on neighbouring countries and we wont have to beg to other countries at times of war.

    @danish_vij @jarves

    Does it mean that if till today our missiles were getting signals from US satellites, in future our missiles will get signals from our own satellite to home into the target? And will it be benefit the common people?

    I am not an expert and i dont know how guidance system of our ballistic missile's works(Possibility is that they dont rely on GPS).Maybe senior members can shed some light here.
    One thing i know is Brahmos is compatible with both Russian and American GPS.

    I thought we had dedicated satellites for spying like the RISAT-1 and RISAT-2. Are you sure these navigation satellites can be used for spying?

    Can you share a link that compares various parameters or can you list down some yourself?

    not sure for that US part o_O:undecided: do u have any source? i guess u dont need a whole navigation system like IRNSS or GPS to track missiles...
    btw as the news piece says:
    so a big yes!:yes4::-)...it will not only help our missiles but common man too....actually it will benefit more to a common man than missile


    ps:i'm not an expert but hope made my point clear!:victory1:

    @TimeToScoot its a regional navigation system for the time being so not comparable to GPS, Glonass or Galileo but more than enough for our military requirements and our threat perception is limited to pakistan and china only:enjoy:

    @thesolar65 sir, AFAIK we don't use GPS for our military purposes we use russian Glonass :tup:

    Yes, in terms of functionality our navigation system is regional and hence limited to South Asia. But what about the performance parameters?

    i thought we already had this navigation system operational. Anyways we'll get it now. So best of luck ISRO!

    i don't think it'l be used for spying as it just covers 1500 km distance beyond indian boundaries. btw can we shift this navigation satellite from one place to other cause by that spying is possible.

    ballistic missiles use dual navigation systems....inertial navigation system ans satellite navigation system for more accuracy!!!
