Indian Space Agency on Sunday said the third orbit raising operation of IRNSS-1I was successfully carried out at 2250 hrs on Saturday. A geosynchronous orbit is when the satellite is in an nearly stationary position with relation to a point on earth. The achieved perigee height (nearest point to the earth) is 35,462.9 km and apogee height (farthest point to the earth) is 35,737.8 km.

Orbit manoeuvres are being performed from ISRO's Master Control Facility (MCF) at Hassan, Karnataka to position the satellite at 55° East longitude in the planned Geosynchronous Orbit with an inclination of 29° to the equator.

India early on Thursday put into orbit navigation satellite IRNSS-1I, a part of Indian satellite navigation system NavIC in copy-book style. The 1,425 kg satellite was carried into space by Polar Satellite Launch Vehicle (PSLV) rocket's "XL" variant.

The 1,425 kg navigation satellite IRNSS-1I was launched from the First Launch Pad at Sriharikota on April 12 at 0404 hrs. The latest launch constitutes the second attempt to launch a backup satellite for IRNSS-1A, which developed problems with its atomic clocks in the second half of 2016.

He also said ISRO was working on launching GSAT - 29 with GSLC Mk III D-2 into the predetermined orbit. Talking about GSAT - 6A, he said that disconnection of communication with satellites for a short time is not uncommon. The satellite was planned to provide a platform for developing technologies such as demonstration of 6-metre S-Band unfurlable antenna, hand-held ground terminals and network management techniques that could be useful in satellite-based mobile communication applications - mainly for the armed forces in remote areas.
