GSAT-19 is an Indian communications satellite launched by the Indian Space Research Organisation aboard an LVM3 on 5 June 2017.^[2]

Satellite and payloads

The satellite will act as a testbed for the modular I-6K satellite bus, carrying experimental technologies such as ion thrusters for manoeuvring and stabilisation, active thermal control using thermal radiators, a miniaturised inertial reference unit, indigenously produced lithium-ion batteries, and C-band traveling-wave-tube amplifiers.^[6]^[7]^[8]

Rather than traditional transponders, GSAT-19 carries four K_u/K_a-band forward link beams and four K_u/K_a-band return link beams, providing much higher data throughput than India's previous communications satellites.^[9]^[10] It additionally carries a Geostationary Radiation Spectrometer (GRASP) payload, which will "monitor and study the nature of charged particles and the influence of space radiation on satellites and their electronic components".^[11]

Orbit raising and station keeping

The satellite was launched aboard the LVM3-D1 rocket in the evening of 5 June 2017 to a geostationary transfer orbit perigee of 180 km (112 mi). This was followed by a series of orbit raising operations (using an on-board LAM and chemical thrusters^[1]) to place the satellite in the intended geostationary orbital slot.
