INSAT-3E will be positioned at 55 deg East longitude in the geostationary orbit. Other INSAT satellite locations are: INSAT-3A at 93.5 deg East longitude, INSAT-2E and INSAT-3B at 83 deg East longitude, INSAT-3C and KALPANA-1 at 74 deg East longitude and GSAT-2 at 48 deg East longitude.

INSAT-3E Mission Profile

Commissioned in 1983, INSAT is the largest domestic communication satellite system in the Asia-Pacific region, providing telecommunications, TV broadcasting, meteorological imaging, disaster warning and satellite aided search and rescue services. INSAT system provides more than 130 transponders in S-band, C- band, extended C-band and Ku-band besides Very High Resolution Radiometers (VHRRs) and Charge Coupled Device (CCD) cameras for meteorological imaging. An experimental satellite, GSAT-2, carrying 4 C-band, two Ku-band and a Mobile Satellite Service transponder along with scientific experimental payloads was launched in May 2003. INSAT-3D, an advanced meteorological satellite and the last in the INSAT-3 series, will be launched in 2004-05. Development of the first two satellites in the INSAT-4 series, INSAT-4A and INSAT-4B, has also commenced. An exclusive satellite for educational purposes, EDUSAT, is also planned for launch by India’s Geosynchronous Satellite Launch Vehicle, GSLV, in 2004.
