I found a board in the museum with the title: INSAT-2E
INSAT-2E, the last of the INSAT-2 series of satellites built by ISRO, is a multipurpose satellite for telecommunication, television broadcasting and meteorological services. The satellite is located at 83 degree east longitude in the geostationary orbit.
- 12 C-band transponders, 7 of which have wide beam coverage and five zonal beam coverages.
- 5 lower extended C-band transponders with zonal beam coverage.
- All channels provide Edge of coverage- Effective Isotropic radiated power (EOC-EIRP) of 36 dBW.
- Very high resolution radiometer (VHRR) with 2 km resolution in visible band and 8 km resolution in infrared and water vapor band.
- Charge Coupled device (CCD) camera operating in visible, near infrared and shortwave infrared band with 1 km resolution.
- Orbit: Geostationary (83 E longitude)
- Dry Mass: 1150 kg
- Mass at Lift-off: 2550 kg
- Size: Cboid 1.9 m x 1.77 m x 2.4 m with solar array on the south and solar sail and boom on the north.
- Length when fully deployed: 26 m
- Spacecraft propulsion: 440 N Liquid Apogee Motor with Nitrogen tetroxide and control and MMH (Mono Methyl Hydrazine) for orbit raising. 3-axis body stabilized in orbit using momentum wheels, sensors, solar flap, magnetic torquer and sixteen Reaction control thrusters of 22 Newtons each.
- Power: Solar array generating 2,050 W. Two 60 Ah Ni-H2 batteries to support fully payload operation during eclipse period.
- Mission life: 12 year.
