WildBlue-1 offers Ka-band Broadband Internet Access via satellite. Operates at 111.1 degrees West in a geostationary orbit. AMC-18 is an SES satellite that provides coverage to North America for many television networks. This satellite operates at 105 degrees West.
Geostationary Transfer OrbitThe GPS-IIR replenishment satellites are produced by General Electric Astrospace (later Martin Marietta and Lockheed Missiles & Space) under a contract issued in 1989, which included 21 satellites based on the commercial AS-4000 bus. These provided improved navigation accuracy and longer autonomous satellite operation than earlier model GPS satellites. The satellites were three-axis stabilized and operated at downlink frequencies of 1572.42 MHz and 1227.6 MHz (L-Band) and 2227.5 MHz (S-Band). Lockheed was responsible for launch and flight operations support of the GPS-IIR through 2006.
Medium Earth OrbitIt was announced that the two satellites had a design life of at least two years, and would be used to probe the space environment, radiation and its effects, record space physical environment parameters, and conduct other related space experiments.
