IRNSS-1 is the first navigational satellite in the Indian Regional Navigational Satellite System series of satellites. The satellite will be the one among the three of the IRNSS series satellites that will be placed in geostationary orbit for navigational purpose.
The satellite has been developed at a cost of 1600 crore (US$290 million), and is expected to be launched on board PSLV-HP by May/June 2013. The satellite will serve two purposes :
- Providing GPS services to the Indian public and
- Providing surveillance facility to the Security Forces.
Each IRNSS 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.
The satellite is planned to be launched from the Satish Dhawan Space Centre in 12 June 2013 1.01PM.
