GSAT-15, India’s latest communications satellite, was launched
successfully by the European Ariane 5 VA-227 launch vehicle in the
early hours of November 11. The 3164 kg GSAT-15 carries communication
transponders in Ku-band and a GPS aided GEO Augmented Navigation
(GAGAN) payload operating in L1 and L5 bands. After countdown lasting
11 hours and 30 minutes, the Ariane 5 launch vehicle lifted off as per
schedule at 3:04 am IST. After 43 minutes and 24 seconds GSAT-15
separated from the Ariane 5 upper stage in an elliptical
Geosynchronous Transfer Orbit with a perigee of 250 km and an apogee
of 35,819 km, inclined at an angle of 3.9 degree to the equator. The
achieved orbit was very close to the intended one. ISRO’s Master
Control Facility at Hassan in Karnataka took over the command and
control of GSAT-15 immediately after its separation from the launch
vehicle. Preliminary health checks revealed its normal health. In the
coming days, orbit raising manoeuvres will be performed to place the
satellite in the Geostationary Orbit (36,000 km above the equator) by
using the satellite’s propulsion system in steps. After the completion
of orbit raising operations, the two solar arrays and the antenna
reflectors of GSAT-15 will be deployed. Later, the satellite will be
put in orbital configuration. It will be positioned at 93.5 deg East
longitude in the geostationary orbit along with the operational
INSAT-3A and INSAT-4B satellites. Later, it is planned to
experimentally turn on the communication payloads of GSAT-15. After
the successful completion of all the in-orbit tests, GSAT-15 will be
ready for operational use.
