GSAT-19 is planned as the payload for the first developmental flight of the indigenous GSLV-Mk III-D1 Launcher. The satellite is planned to carry Ka and Ku band payload along with a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components. GSAT-19 satellite will employ advanced spacecraft technologies including bus subsystem experiments in Electrical propulsion System, indigenous Li ion battery, indigenous Bus bars for power distribution, etc.

The satellite is scheduled to be launched during First Quarter of 2017 by GSLV-Mk III-D1 Launcher from SDSC SHAR, Sriharikota.
