    The Indian Regional Navigational Satellite System (IRNSS) is an autonomous regional GPS-based satellite navigation system being developed by the Indian Space Research Organisation (ISRO) and it would be under the total control of the Govt of India. The IRNSS’s R & D programme was approved in May 2006. Total project cost is Rs16 billion and the project is due for completion by 2012. The IRNSS will comprise a constellation of seven GPS navigation satellites placed in geostationary orbit that will provide an absolute position accuracy of better than 10 metres throughout India and within a region extending approximately 2,000km around India.

    On the other hand, the GPS Aided Geo Augmented Navigation or GPS and Geo Augmented Navigation system (GAGAN) is a planned implementation of a regional satellite-based augmentation system (SBAS) by the Govt of India to improve the accuracy of a GNSS receiver by providing reference signals. The Rs7.74 billion project is being implemented in three phases since 2008 by the Airports Authority of India (AAI) with the help of ISRO. The goal is to provide GPS-based navigation cues for all phases of flight over the Indian airspace and in the adjoining regional area. It is applicable to safety-to-life operations, and meets the performance requirements of international civil aviation regulatory bodies. The final, operational phase of GAGAN is due for completion by May 2011.

    IRNSS has a Good Chance of Being Operationalised Replacing GPS as the Guidance system in our Short Range Ballistic Missiles... GPS cannot be Relied upon in hostile Situations..

    Not Really, It is not a Global Positioning Satellite, Its Just a REGIONAL Navigation systems,IRNSS will cover Indian subcontinent, South east Asia, Iran, Indian Ocean, China, some part of Australia, and Arabs ...

    And We have Something called "GINS" Under Development, which Means "Global Indian Navigation Satellite" a Complete replacement to GPS...

    There are two scales of gps civilian and military... Civilan GPS has a accuracy of 3meters while military gps has a cep of 1meter ..
    India cannot access military gps so it uses civilian gps for course correction before some other form of guidance takes over...
    Gagan is a regional positioning system, that may be integrated with glonass for military purposes...
    But whatever it may be Gagan will be more accurate than gps due to advances in sensors... Probably on lines of military gps maybe a little better...
