GSAT-15, India’s most recent interchanges satellite, was propelled effectively by the European Ariane 5 VA-227 dispatch Vehicle in the early morning hours of November 11, 2015. The 3164 kg GSAT-15 conveys correspondence transponders in Ku-band and in addition a GPS Aided GEO Augmented Navigation (GAGAN) payload working in L1 and L5 groups.
After a smooth commencement enduring 11 hours and 30 minutes, the Ariane 5 dispatch vehicle lifted off ideal on plan at 0304 hrs (3:04 am) IST.
Following a flight of 43 minutes and 24 seconds, GSAT-15 isolated from the Ariane 5 upper stage in a curved Geosynchronous Transfer Orbit (GTO) with a perigee (closest point to Earth) of 250 km and an apogee (most distant point to Earth) of 35,819 km, slanted at an edge of 3.9 degree to the equator.
The accomplished circle was near the planned one.
ISRO’s Master Control Facility (MCF) at Hassan in Karnataka assumed control over the order and control of GSAT-15 instantly after its partition from the dispatch vehicle.
Preparatory wellbeing checks of the satellite uncovered its ordinary wellbeing.
In the coming days, circle raising moves will be performed to put the satellite in the Geostationary Orbit (36,000 km over the equator) by utilizing the satellite’s impetus framework in steps.
After the consummation of circle raising operations, the two sun based clusters and both the recieving wire reflectors of GSAT-15 will be sent. Following this, the satellite will be placed in its last orbital arrangement.
GSAT-15 will be situated at 93.5 deg East longitude in the geostationary circle alongside the operational INSAT-3A and INSAT-4B satellites. Afterward, it is wanted to tentatively turn on the correspondence payloads of GSAT-15. After the effective fruition of all the in-circle tests, GSAT-15 will be prepared for operational utilize.
