Mission Objectives:
The Indian Regional Navigation Satellite System (IRNSS) consists of a constellation of seven satellites and a ground segment for positioning and timing applications. IRNSS is under development by the Indian Space Research Organisation (ISRO). INRSS will include three satellites in geostationary orbit and four satellites in geosynchronous orbit, transmitting L-band and S-band signals and providing coverage primarily for the Indian land mass.
SLR tracking data will be used for orbit determination and calibration of the orbit determined from other sources.
Mission Instrumentation:
INRSS satellites will have the following instrumentation onboard:
- Atomic clocks
- L and S-band transmitters
- Retroreflector array
