GLOMR [DARPA]
GLOMR [DARPA] |
GLOMR (Global Low Orbiting Message Relay) 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. The spacecraft is a small, 62-sided polyhedron without stabilisation. 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.
