GSat 2

GSat 2 [ISRO]

GSAT-2 is a 2000 kg class experimental communication satellite onboard the second developmental test flight of India's Geosynchronous Satellite Launch Vehicle, GSLV Mk.1 (2). The satellite carries four C-band transponders, two Ku-band transponders and a Mobile Satellite Service (MSS) payload operating in S-band and C-band for forward link and return link respectively.

Besides the communication payloads, GSAT-2 carries four piggyback experimental payloads: 

• Total Radiation Dose Monitor (TRDM) to compare the estimated radiation doses inside the satellite with the directly measured radiation doses using a Radiation Sensitive Field Effect Transistor (RADFET)
• Surface Charge Monitor (SCM) to indicate the state of the charging environment in the vicinity of the satellite
• Solar X-ray Spectrometer (SOXS) to study the solar flare emission in 4 keV.- 10 MeV energy range using state of the art semiconductor devices and Phoswich Scintillation Detector
• Coherent Radio Beacon Experiment (CRABEX) to investigate the spatial structure, dynamic and temporal variations of Ionosphere and several aspects of equatorial electrodynamics
