About GSAT-17
-
- GSAT-17 was inducted into the INSAT/GSAT system from Kourou, French Guiana by Ariane-5 VA-238.
- Weighing 3477 kg at lift-off, GSAT-17 carries Payloads in Normal C-band, Extended C-band and S-band to provide various communication services.
Source : ISRO - GSAT-17 also carries equipment for metereological data relay and satellite based search and rescue services being provided by earlier INSAT satellites.
- GSAT-17 is designed to provide continuity of services on operational satellites in C-band, Extended C-band and S-bands.
- GSAT-17 was launched into a Geosynchronous Transfer Orbit (GTO).
- The designed in-orbit operational life of GSAT-17 is about 15 years.
Significance of GSAT-17
- The latest communication satellite, is the third satellite launch by ISRO this month.
- The other two were the first developmental flight of GSLV MkIII and PSLV C-38 missions, both from Sriharikota spaceport.
- It carried payloads in Normal C-band, Extended C-band and S-band to provide various communication services.
- ISRO has been dependent on Ariane-5 rocket for carrying its heavier satellites, until the development of GSLV Mk III for this purpose.
- provides the continuity in services of ageing two satellites, as well as augmenting our transponder capability, and widening our horizon to mobile satellite services
Indian National Satellite System (INSAT)
