IRNSS is only a regional navigation satellite and will in no way be a direct competitor to the Global Navigation Satellite Systems like GPS or GLONASS. India has already launched its own SBAS system in GAGAN (GPS Aided Geo Augmented Navigation) and the latest regional navigation satellite system is only going to help the GNSS Industry in the country grow. The design of IRNSS allows for an additional 3 satellites to be added to the original 7 satellites that are planned to be set into orbit by the end of 2015. However it would not be possible for the system to be converted into a Global system in the future. With launch failures of GLONASS satellites, it looks like GPS is set to be the standard for the time being, Beidou from China being the only realistic competition that can arise in the future with GALILEO struggling to move forward.
