India's GSAT-10 Communication Satellite Launched Successfully

Introduction

The launch of ISRO's 101st space mission, GSAT-10 satellite, has been a success. At 3400 kg, GSAT-10 is the heaviest Indian satellite that ISRO has built.
After a smooth countdown lasting 11 hours and 30 minutes, the Ariane-5 launch vehicle lifted off right on schedule at the opening of the launch window at 0248 hrs IST today (September 29,2012). After a flight of 30 minutes and 45 seconds, GSAT-10 was injected into an elliptical Geosynchronous Transfer Orbit (GTO), very close to the intended one.
ISRO's Master Control Facility (MCF) took over the command and control of the GSAT-10 immediately after the injection. Preliminary health checks on the various subsystems of the satellite, namely, Power, Thermal, Command, Sensors, Controls, etc., were performed and all the parameters were found satisfactory. Following this, the satellite was oriented towards the Earth and the Sun using the onboard propulsion system. The satellite is in good health.
In the coming five days, orbit raising maneuvers will be performed to place the satellite in the Geostationary Orbit with required inclination with reference to the equator. The satellite will be moved to the Geostationary Orbit (36,000 km above the equator) by using the satellite propulsion system in a three step approach.
After the completion of orbit raising operations, the two solar panels and both the dual gridded antenna reflectors of GSAT-10 will be deployed for further tests and operations. It is planned to experimentally turn on the communication payloads in the second week of October 2012.
After the successful completion of all in-orbit tests, GSAT-10 will be ready for operational use by November 2012. GSAT-10 will be positioned at 83deg East orbital location along with INSAT-4A and GSAT-12. The operational life of GSAT-10 is expected to be 15 years nominal.
GSAT-10 Satellite has 30 Communication Transponders [12 in Ku-band, 12 in C-band and 6 in Extended C-Band]. Besides, it has a Navigation payload "GAGAN" that would provide GPS signals of improved accuracy (of better than 7 meters) to be used by the Airports Authority of India for Civil Aviation requirements. GSAT-10 is the second satellite in INSAT/GSAT constellation with GAGAN payload after GSAT-8, launched in May 2011.
