IRNSS-1C
IRNSS-1C
Navigational satellite
IRNSS-1C is the third out of seven in the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A and IRNSS-1B. The IRNSS constellation of satellites is slated to be launched to provide navigational services to the region. It was launched on 15 October 2014 at 20:02 UTC by PSLV-C26 and will be placed in geostationary orbit.[1][3][4]

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.[5]
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 (GPS) and Galileo systems.[3] 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.[6] An update from ISRO's official Facebook page on 18 October 2014 states that
