'''INSAT-2E''' is an Indian geostationary [[communications satellite|communications]] and [[weather satellite]] which is operated by the [[Indian National Satellite System]].<ref name="GSP"/> It is positioned in [[geostationary orbit]] at a [[longitude]] of 83° East, from where it is used to provide communications services to [[Asia]] and Australia. 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.<ref>{{cite web |url=http://www.isro.org/satellites/insat-2e.aspx |title=INSAT-2E |publisher=Indian Space Research Organisation |access-date=2009-08-08 |archive-url=https://web.archive.org/web/20130818091155/http://isro.org/satellites/insat-2e.aspx |archive-date=18 August 2013 |url-status=dead }}</ref>

The communications payload aboard INSAT-2E consists of seventeen G/H band (IEEE C band) [[transponder]]s.<ref name="GSP">{{cite web |url=http://space.skyrocket.de/doc_sdat/insat-2e.htm |title=Insat 2E / Intelsat APR-2 |first=Gunter |last=Krebs |publisher=Gunter's Space Page |access-date=2009-08-08}}</ref> At launch the satellite had a mass of {{convert|2550|kg}}, with an expected operational lifespan of 12 years.<ref name="UCS">{{cite web |url=http://www.ucsusa.org/nuclear_weapons_and_global_security/space_weapons/technical_issues/ucs-satellite-database.html |title=UCS Satellite Database |publisher=Union of Concerned Scientists |date=1 July 2009 |access-date=2009-08-08}}</ref> 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 4|Ariane 42P]] carrier rocket flying from [[ELA-2]] at the [[Guiana Space Centre]]. The launch occurred at 22:03 UTC on 2 April 1999.<ref name="JSR-LL">{{cite web |url=http://planet4589.org/space/log/launchlog.txt |title=Launch Log |last=McDowell |first=Jonathan |publisher=Jonathan's Space Page |access-date=2009-08-08}}</ref> Following launch, it raised itself into [[geostationary orbit]] using liquid-fuelled [[apogee motor]].
