Like GPS, Glonass, and other similar systems, IRNSS will be used to provide navigation that is accurate to within 20 meters, and will be used by both citizens and the nation's defense network alike.

Its predecessors, IRNSS-1A, 1B, 1C and 1D which were launched by PSLV-C22, PSLV-C24, PSLV-C26 and PSLV-C27 in July 2013, April 2014, October 2014 and March 2015 respectively.

The India Space Research Organisation's IRNSS-1I navigation satellite is attached to the agency's Polar Satellite Launch Vehicle booster ahead of the craft's April 12, 2018, launch.

Even before IRNSS-1H was lost, IRNSS-1I was being prepared for launch in late 2017 or early 2018, in order to provide extra redundancy on orbit should another satellite malfunction.

IRNSS-1H will use modified versions of the same clocks as its predecessors. IRNSS-1H is a 1,425-kilogram (3142 lb) satellite which is expected to provide ten years of service.

At the end of 450 seconds of firing, the satellite’s apogee was boosted from 20,630 km to 24,760 km and the perigee went up from 283 km to 299 km, said M. Nageswara Rao, Project Director, IRNSS.

SCIENCE News: IRNSS-1A is the first navigational satellite developed by the Indian Regional Navigation Satellite System (IRNSS) in series of satellites been placed .

The 1C satellite is the third satellite out of a total of seven which will constitute the IRNSS. The 1A and 1B were launched in July 2013 and April 2014. According to ISRO, the 1C satellite has a ...
