AsiaSat 3S, was ageosynchronouscommunications satellite forAsiaSat ofHong Kong to provide communications and television services all acrossAsia, theMiddle East andOceania.
In March 1998, AsiaSat ordered a replacement satellite, for US$195 million, fromHughes Space and Communications. Designated AsiaSat 3S, the new satellite is a replica ofAsiaSat 3.[1]
AsiaSat 3S was launched for AsiaSat by aProton-K /DM-2Mlaunch vehicle on 21 March 1999, at 00:09:30UTC, destined for an orbital location at 105.5° East.[2] A replacement for Asiasat 3, placed in the wrong orbit by a Proton launch in 1997, Asiasat 3S carriedC-band andKu-bandtransponders. The Blok DM-2M upper stage placed the satellite in aGeostationary transfer orbit (GTO). Asiasat's on-board R4D-11-300apogee engine was then used to raiseperigee to geostationary altitude.[3] It replacedAsiaSat 1 on 8 May 1999.[1]
It was replaced byAsiaSat 7.
