Intelsat 2, formerlyPAS-2, was acommunications satellite operated byIntelsat which spent most of its operational life serving thePacific Rim market from alongitude of 169° East.[2] Launched in July 1994, the satellite was operated byPanAmSat until it merged with Intelsat in 2006. The spacecraft was renamed, along with the rest of PanAmSat's fleet, on 1 February 2007.[3]

Satellite description

[edit]

PAS-2 was constructed by theHughes Aircraft Corporation, based on theHS-601satellite bus. It had a mass at launch of 2,920 kg (6,440 lb), which decreased to around 1,727 kg (3,807 lb) by the time it was operational. Designed for an operational life of 15 years, the spacecraft was equipped with 20C-band and 20Ku-bandtransponders.[3] Its twosolar panels, which had a span of 26 m (85 ft) generated 4.7kW of power when the spacecraft first entered service, which was expected to drop to around 4.3 kW by the end of the vehicle's operational life.[2]

Launch

[edit]

Arianespace launched PAS-2, using anAriane 4launch vehicle, flight number V65, in the Ariane 44L H10+ configuration. The launch took place fromELA-2 at theCentre Spatial Guyanais at 23:05:32 UTC on 8 July 1994. The satellite was placed into ageosynchronous transfer orbit (GTO), from which it raised itself intogeostationary orbit by means of an R-4D-11-300apogee motor.[3]

Intelsat 2

[edit]

Intelsat 2 (PAS-2), launched in January 1996, the satellite was operated byPanAmSat until it merged with Intelsat in 2006. The spacecraft was renamed, along with the rest of PanAmSat's fleet, on 1 February 2007.[3]

Decommissioning

[edit]

Intelsat 2 was removed fromgeostationary orbit in February 2011, being placed intograveyard orbit on 28 February 2011.[4] Manoeuvring into graveyard orbit did not fully deplete the satellite's propellant as had been expected, so engineering operations continued until July 2011 in order to exhaust the remaining supply. The satellite was then decommissioned and powered down.[5]
