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

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.
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.
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.
