- IRNSS project director P. Kunhikrishnan said that once IRNSS-1D is in place, the four initial satellites would meet the minimum requirement to start operations of the IRNSS system.
- ISRO said the IRNSS is designed to provide positioning information accurate to within 20 meters to users in a region that includes all of India and extends to 1,500 kilometers beyond the nation’s borders. IRNSS ground control and signal monitoring and ranging stations have been established in 15 locations across India.
- When fully deployed by sometime in 2016, the 14.2 billion rupee ($226 million) IRNSS will consist of seven nearly identical satellites, three in geostationary orbit, two in inclined geosynchronous orbits and two spares. The first three satellites, launched last year, are in position and functioning well, according to ISRO.
