'''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]].<ref name="isrobrochure"/><ref name="skyrocket">{{cite web|url=http://space.skyrocket.de/doc_sdat/irnss.htm|title=IRNSS |publisher=space.skyrocket.de |access-date=6 December 2014}}</ref><ref>{{cite news | url=http://www.thehindu.com/sci-tech/science/indias-pslvc26-rocket-launches-third-navigation-satellite-irnss1c/article6504091.ece | title=India launches third navigation satellite | newspaper=The Hindu | date=16 October 2014 | access-date=16 October 2014| last1=Ravikiran | first1=G. }}</ref>

== Satellite ==
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.<ref name="irnss1b_itv">{{cite news | url=http://www.indiatvnews.com/news/india/isro-after-gslv-launch-pslv-c-with-irnss-b-likely-in-march--32118.html | title=ISRO: After GSLV launch, PSLV C24 with IRNSS-1B likely in March | work=India | date=5 January 2014 | access-date=6 January 2014 | archive-date=6 January 2014 | archive-url=https://web.archive.org/web/20140106193940/http://www.indiatvnews.com/news/india/isro-after-gslv-launch-pslv-c-with-irnss-b-likely-in-march--32118.html | url-status=dead }}</ref>

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 [[L band|L5]] and [[S-band]]. The design of the payload makes the IRNSS system inter-operable and compatible with [[Global Positioning System]] (GPS) and [[Galileo (satellite navigation)|Galileo]] systems.<ref name="skyrocket"/> 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]].<ref>{{Cite news|url=http://www.thehindu.com/sci-tech/science/indias-pslvc26-rocket-launches-third-navigation-satellite-irnss1c/article6504091.ece|title = India launches third navigation satellite|newspaper = The Hindu|date = 16 October 2014|last1 = Ravikiran|first1 = G.}}</ref> 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:
