IRNSS-1D is a satellite in the Indian Regional Navigational Satellite System (IRNSS) constellation. The satellite is the fourth of seven in the constellation, launched after IRNSS-1A, IRNSS-1B and IRNSS-1C. The satellite is the only satellite in the constellation slated to provide navigational services to the region. The satellite will be placed in geosynchronous orbit.[4] It was launched successfully on 28 March 2015 onboard ISRO's PSLV-C27 from Satish Dhawan Space Center, Sriharikota.[5][6][7]
Satellite
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 approximately ₹14 billion.[9]
