Abstract

In space missions, geographically separated TTC stations support data reception between launch vehicle and earth in real time. GSO-based INSAT segment can act as telemetry data relay platform between the host vehicle and the ground station. It has better coverage for supporting TTC requirement. Telemetry via INSAT (TIST) is used to overcome the visibility constraints of conventional TTC ground stations, ship-borne terminals and air-borne terminals, especially in the descent phase. TIST covers events in such scenarios without any hindrance by transmitting data to GSO satellite and receiving it back at ISRO earth stations. It employs digital modulation with channel coding for establishing the link from the launch vehicle to satellite. The satellite transponder upconverts the signal and transmits the information in real time to ISRO ground station. The system was tested in the RLV-TD mission of ISRO and transmitted the critical vehicle parameters in real time in order to evaluate the performance of the vehicle. This scheme is the first of its kind in ISRO launch vehicle, where communication is established between a moving launch vehicle and a single satellite in GSO orbit.
