Summary
Olympus was a communication and experimental satellite launched by ESA on July 12, 1989, from Guiana Space Centre using an Ariane 3 launch vehicle. The spacecraft measures 5.6 meters in length with a diameter of 2.7 meters and span of 25.7 meters. It has a dry mass of 1200 kg and was launched with a total mass of 2595 kg. Olympus is equipped with multiple Ku-band and Ka-band transponders, including BSS and SMS-transponders as well as a propagation beacon operating in Ku-/Ka-bands. Power is supplied by two deployable solar arrays and batteries. The satellite's design includes a box shape with two panels and was manufactured by BAES (British Aerospace). It had a planned lifetime of 5 years and used an R-4D-11 motor for propulsion, orbiting in support of communication purposes.
