GLOMR ( Global Low Orbiting Message Relay , also GLOMAR ) was a military satellite developed by DARPA to demonstrate the ability of remote ground sensors to read, store and forward data.
construction
The satellite is a 62-sided, 60 cm tall and 52 kg heavy polyhedron without stabilization. Components are the transmitter, receiver, batteries and an associated battery management system. The satellite was controlled by two CMOS microprocessors. While one took over communication, the other was responsible for telemetry, appointments and commands. The energy supply was secured by solar cells attached to the satellite shell.
history
GLOMR launched on April 29, 1985 with Space Shuttle Challenger as part of the STS-51-B mission. Due to a battery problem, the satellite was not released during the mission and was taken back to earth. The STS-61-A mission, also launched on October 30, 1985 with the Challenger, successfully deployed the satellite in orbit. After 14 months, the satellite burned up on December 26, 1986 when it re-entered the earth's atmosphere. The cost of the entire mission was less than a million dollars. A further development of the probe began on April 5, 1990 under the name SECS .
