IDRSS (Indian Data Relay Satellite System) is an Indian geostationary data relay satellite system consisting of two geostationary satellites. IDRSS will facilitate relay of information between various Indian spacecraft, in-flight launch vehicle monitoring and assist Indian Human Spaceflight Programme.
The main objectives of IDRSS are:
- TTC, Data, Audio and Video links to Gaganyaan
- TTC links to LEO satellite
- Data transfer from Antarctica Ground Stations
The satellite is configured with data relay payloads operating in S, Ka and Ku bands. The satellite employs a 2.5 m deployable Cassegrain Antenna System operating in dual frequency bands (S and Ka bands) as well as a 1.5 m fixed Cassegrain Antenna System operating in Ku and Ka frequency bands. The deployable antenna system will have interface with the satellite by means of a deployable, pointing and tracking mechanism along with a S band rotary joint. The satellite bus is based on the I-2K (I-2000) Bus extended bus and will be compatible for launch onboard the GSLV Mk.2(4) Launch Vehicle.
