PanAmSat-1R, Amsat-P3D, STRV 1C & 1D

Space Technology Research Vehicle or STRV was a series of British microsatellites which operated in elliptical orbits around the Earth. The satellites were built by the Defence Research Agency at Farnborough, for the UK Ministry of Defence.

AMSAT-OSCAR-40, also known as AO-40 or simply OSCAR 40, was the on-orbit designation of an amateur radio satellite of the OSCAR series. Prior to launch, the spacecraft was known as Phase 3D or "P3D". AO-40 was built by AMSAT.

PanAmSat-1R, also known as PAS 1R, was ordered in August 1997. The satellite carries 72 active transponders: 36 in C-band and 36 in Ku-band. That is three times the capacity of PAS 1, the spacecraft it replaced. PAS-1R was designed for an end-of-life power of more than 14 kW. The satellite provides coverage to four continents from its slot over the Atlantic Ocean. PAS-1R was launched in 2000 on board an Ariane-5G rocket. Intelsat changed the name of the PAS satellites to Intelsat effective to 1. February 2007. PAS 1R suffers from a generic failure of the early BSS-702 model: the fogging of the concentrator mirrors on the solar arrays leads to reduced available power.
