Other Designations: Global Low Orbiting Message Relay. Class: Communications. Type: Military. Nation: United States. Agency: DARPA. Manufacturer: Defense Systems Inc. (now CTA).

GLOMR was a DARPA mission designed to demonstrate the ability to read out, store, and forward data from remote ground-based sensors. The satellite was first scheduled for deployment from STS-51B, but a battery problem forced a return to Earth for repair. Reflown and deployed from STS-61A, the vehicle finally re-entered after 14 months. The total price was less than 1 million dollars. Spacecraft: Small, 62-sided polyhedron. Unstabilised. Design included redundant transmitters, receivers, batteries, and battery charge control systems. It had two CMOS microprocessors - one for communications control, the other for scheduling, mass memory, housekeeping, and mission control, telemetry, and command functions.
