It also carries two meteorological instruments; the Very High Resolution Radiometer, and a CCD camera capable of returning images with a resolution of one kilometre.[2] The communications payload aboard INSAT-2E consists of seventeen G/H band (IEEE C band) transponders.[3] At launch the satellite had a mass of {{convert|2550|kg}}, with an expected operational lifespan of 12 years.[4] Some of its transponders are leased to Intelsat, who operate them under the designation Intelsat APR-2. INSAT-2E was launched by Arianespace, using an Ariane 42P carrier rocket flying from ELA-2 at the Guiana Space Centre. The launch occurred at 22:03 UTC on 2 April 1999.[5] Following launch, it raised itself into geostationary orbit using liquid-fuelled apogee motor. Its final insertion burn occurred at 07:38 UTC on 8 April.[6] Following insertion, it was positioned at a longitude of 83° East. See also{{Portal|Spaceflight}}
