GSAT-19 is a commercial communications satellite operated by the Indian space agency ISRO .
He was born on June 5, 2017 at 11:58 UTC with the first -Mark III GSLV - carrier rocket from the rocket launch site Satish Dhawan Space Center in a geostationary brought orbit.
The three-axis stabilized satellite is 4 Ku-band - and Ka-band - transponders (8 illumination areas in the Ku-band and 2-stroke illumination areas m- 2.0 in the Ka-band with two and a 1.4-m antenna) equipped. It was based on the satellite bus I-3K ISRO built and has a design life of 10 years. The main task of the spacecraft is primarily a technology test to test new systems for use on future Indian communications satellites. To test technologies include more miniaturized forms of heat exchangers , which are intended for better thermal control of the satellite, as well as micro-electromechanical accelerometer ( MEMS ) and fiber optics - gyroscopes , which are to improve the positioning of the satellite. Also on board GSAT-19 is the Geostationary Radiation Spectrometer (GRASP), which will detect charged particles in the vicinity of the satellite. This is to help determine the effect of these particles on the satellite and its electrical systems.
