The satellite will help 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-1C satellite will have 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 and Galileo systems. The satellite is powered by two solar arrays, which generate up to 1,660 watts, and has a life-time of ten years.
IRNSS-1C was launched successfully on 16 October 2014 at 1:32 am IST from Satish Dhawan Space Centre in Sriharikota. An update from ISRO's official Facebook page on 18 October 2014 states that
