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] SatelliteThe 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 Navigation Satellite IRNSS 1C Update: The second orbit raising operation of IRNSS-1C is successfully completed by firing the Apogee Motor for 1,563 seconds. The current orbital parameters are: See also{{Portal|Spaceflight}}
