GSat 19

GSat 19 [ISRO]

GSAT-19 is an experimental Indian geostationary communications satellite.

GSAT-19E is to act as test bed for several new technologies like the I-6K unified modular bus, deployable thermal radiators, electrical propulsion, indigenous Li-Ion batteries and C-band TWTAs, optical payload, etc.

The 3136 kg satellite carries a Ka- and Ku-band high throughput 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 also features certain advanced spacecraft technologies including miniaturised heat pipe, fibre optic gyro, Micro Electro-Mechanical Systems (MEMS) accelerometer, Ku-band TTC transponder, as well an indigenous Lithium-ion Battery.

The satellite was launched in early 2017 on the maiden orbital flight of the GSLV Mk.3 launch vehicle.
