The satellite will help in augmenting the satellite based navigation system of India which is currently under development. The navigational system so developed will be a regional one targeted towards South Asia. The satellite will provide navigation, tracking and mapping services.[8]
IRNSS-1D 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 Global Positioning System (GPS) and Galileo.[4] The satellite is powered by two solar arrays, which generate power up to 1,660 watts, and has a life-time of ten years.
Cost
The total cost of the mission was estimated at ₹14 billion.[9]
Retirement
At its end-of-mission, the IRNSS-1D satellite was raised to a graveyard orbit nearly 600 km above the geostationary belt and passivated. Unlike other ISRO geostationary satellites who were disposed off in super-synchronous orbits, IRNSS-1D was the first to be disposed off in an inclined geosychronosis orbit.[10]
