GSat 1

GSat 1 [ISRO]

While the first developmental test flight of the GSLV is primarily intended for validating the vehicle design and its performance parameters as well as the associated ground infrastructure, the flight opportunity is also made use of to place an experimental satellite GSAT-1 weighing about 1540 kg. GSAT-1 will be used to prove new spacecraft elements like ten Newton Reaction Control Thrusters, Fast Recovery Star Sensors and Heat Pipe Radiator Panels to validate them before using them in the ISRO operational ISRO satellites like IRS and INSATs. GSAT-1 will also carry two C-band transponders employing 10 W Solid State Power Amplifiers (SSPAs), one C-band transponder using 50 W Travelling Wave Tube Amplifier (TWTA) and two S-band transponders using 70W TWTA.

GSAT-1 will be used for demonstrating digital audio broadcast, internet services, compressed digital TV experiments and developmental communication.
