HS-601 The Boeing 601 (sometimes referred to as the BSS-601, and previously as the HS-601) is a communications satellite satellite bus, bus designed in 1985 and introduced in 1987 by Boeing Satellite Development Center, Hughes Space and Communications C ...
satellite bus A satellite bus (or spacecraft bus) is the main body and structural component of a satellite or spacecraft, in which the payload and all scientific instruments are held. Bus-derived satellites are opposed to specially produced satellites. Bus- ...

Ku-band The Ku band () is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under" (originally german: Kurz-unten), because it is the lower part of the ori ...
transponders In telecommunications, a transponder is a device that, upon receiving a signal, emits a different signal in response. The term is a blend of ''transmitter'' and ''responder''. In air navigation or radio frequency identification, a flight tran ...

Intelsat 2

Intelsat 2 (PAS-2), launched in January 1996, the satellite was operated by
PanAmSat The former PanAmSat Corporation founded in 1984 by Reynold (Rene) Anselmo, was a satellite service provider headquartered in Greenwich, Connecticut, United States. It operated a fleet of communications satellites used by the entertainment ind ...

Decommissioning

Intelsat 2 was removed from geostationary orbit in February 2011, being placed into
graveyard orbit A graveyard orbit, also called a junk orbit or disposal orbit, is an orbit that lies away from common operational orbits. One significant graveyard orbit is a supersynchronous orbit well beyond geosynchronous orbit. Some satellites are moved into ...
on 28 February 2011. 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.
