Artemis
AKA: Advanced Relay TEchnology MISsion. Status: Operational 2001. First Launch: 2001-07-12. Last Launch: 2001-07-12. Number: 1 . Gross mass: 3,105 kg (6,845 lb). Unfuelled mass: 1,567 kg (3,454 lb).
It carried the Silex laser communications experiment, an S-band inter-orbit link, a Ka-band data relay package, a large L-band antenna for mobile services, and an L-band navigation package. The 3105 kg satellite was equipped with an Astrium S400 400 N liquid apogee engine with 1538 kg of propellants; a set of 10 N RCS thrusters; and four 20 mN ion thrusters with 40 kg of xenon. The 2.5 kW spacecraft was to provide voice and data communications between mobile phones in Europe and North America, and act as a relay satellite between low-Earth orbiters and ground stations. Eventually, as part of the planned EGNOS system (to be operational by about 2010) it was to provide navigation/location determination as an independent European counterpart to the GPS and GLONASS fleets.
Electric System: 2.50 average kW.
