ISRO Successfully Launches GSAT-17
ISRO successfully launches GSAT-17 communication Satellite onboard the Ariane-5 launch vehicle from the Guiana Space Center at French Guiana on June 28. GSAT-17 will be the ISRO’s third satellite that is launched within a span of three months.
The 3,477-kg GSAT 17 communication satellite will be placed in the geostationary orbit and will have a mission life of 15 years. The satellite will be an addition to the current fleet of 17 Indian communication satellites that are already providing services from space. Apart from providing communication services, the satellite will provide meteorological and satellite-based data to help rescue services which were earlier provided by geostationary satellites called Indian National Satellite System (INSAT). GSAT-17 will provide continuity of services of operational satellites in C, extended C and S bands Once launched, ISRO’s Master Control Facility at Hassan in Karnataka and Bhopal in Madhya Pradesh will take over and place the satellite in geostationary orbit. GSAT-17 was designed and assembled at the ISRO Satellite Centre in Bengaluru. In addition, GSAT-17 will also launch communication satellite Hellas Sat 3-Inmarsat S EAN. Hellas Sat 3 will provide directly to home television and telecom services across Europe, West Asia and South Africa. Inmarsat is set to provide in-flight Internet facilities for European airlines.
