American communications satellite. The LM 700 had its first use in the Iridium system, a commercial communications network comprised of a minimum of 66 LEO spacecraft.

AKA: Iridium. Status: Operational 1997. First Launch: 1997-05-05. Last Launch: 2002-06-20. Number: 97 . Gross mass: 689 kg (1,518 lb). Height: 4.00 m (13.10 ft).

The system used L-Band to provide global communications services through portable handsets. A total of 125 spacecraft were to be built by Lockheed for more than $700M. However Iridium went bankrupt in 1999 after 90 had been launched. However the constellation remained in use for specialized users and a launch in 2002 replenished the constellation.

The spacecraft itself was three-axis stabilized with a hydrazine propulsion system. Power was supplied by two solar panels with 1-axis articulation. The system employed L-Band using FDMA/ TDMA to provide voice at 4.8 kbps and data at 2400 bps with 16 dB margin. Each satellite had 48 spot beams for Earth coverage and used Ka-Band for crosslinks and ground commanding.
