INSAT-2E is an Indian geostationarycommunications andweather satellite which is operated by theIndian National Satellite System.[2] It is positioned ingeostationary orbit at alongitude of 83° East, from where it is used to provide communications services toAsia and Australia. It also carries two meteorological instruments; theVery High Resolution Radiometer, and aCCD camera capable of returning images with a resolution of one kilometre.[3]
The communications payload aboard INSAT-2E consists of seventeen G/H band (IEEE C band)transponders.[2] At launch the satellite had a mass of 2,550 kilograms (5,620 lb), with an expected operational lifespan of 12 years.[4] Some of its transponders are leased toIntelsat, who operate them under the designationIntelsat APR-2.
INSAT-2E was launched byArianespace, using anAriane 42P carrier rocket flying fromELA-2 at theGuiana Space Centre. The launch occurred at 22:03 UTC on 2 April 1999.[5] Following launch, it raised itself intogeostationary orbit using liquid-fuelledapogee motor. Its final insertion burn occurred at 07:38 UTC on 8 April.[6] Following insertion, it was positioned at alongitude of 83° East.
INSAT-2E is using ultra-light Magnesium-lithium alloys developed byDMRL.The Magnesium-lithium sheets were supplied to ISAC, Bangalore center.[7]
