Paksat-MM1 (formerly known as AsiaSat 4) was a leasedcommunications satellite operated bySUPARCO, Pakistan's space agency. It was provided byAsia Satellite Telecommunications Company (AsiaSat), aHong Kong–based satellite operator.[1]
Initially stationed at 122° East longitude, Paksat-MM1 was later relocated to 38.2° East to better serve Pakistan and the surrounding region. During most of its operational life at 122° East, it providedfixed satellite services, including broadcasting, audio, and data transmission, toAsia and thePacific Ocean.[2]
AsiaSat 4 was built byHughes Space and Communications, for US$220 million, which by the time of its launch had become part ofBoeing Satellite Systems. It is based on theHS-601HPsatellite bus. At launch, it had a mass of 4,137 kg (9,121 lb),[2] and a design life of fifteen years. It carries twenty eightC-band and twentyKu-bandtransponders.[2] It was planned for late 1999, but was delayed because of the Asian crisis. Construction started in September 2000.[3]
AsiaSat 4 was launched by anAtlas 3B SEClaunch vehicle with theCentaurupper stage fromCape Canaveral Air Force Station (SLC-36B) at 00:47:01UTC on 12 April 2003.[4]
AsiaSat 4 was insured for launch and first year in orbit. The AsiaSat 4 was replaced byAsiaSat 9 in 2017.[5]
In February 2018 it was leased by PakSat International, a subsidiary of SUPARCO (Pakistan's space agency), from the Asia Satellite Telecommunications Company (AsiaSat) . Previously positioned at 122° East longitude, it was relocated to 38.2° East to serve Pakistan's needs. Paksat renamed it Paksat-MM1 (Paksat-Multi Mission 1) and began operations in March 2018.[2]
After the lease expired, the satellite was returned to China and relocated to 147.5° East. As of 29 August 2024 (according to flysat.com), it is no longer operational and has been replaced byPakSat-MM1R, a new satellite launched on 30 May 2024.[6]
