Mars Observer Ground Support Equipment Collection, 1986-1994.

http://www.worldcat.org/oclc/733102167

The collection arrangement includes 117 folders in 16 boxes. This consists of ground support equipment material on the Mars Observer Spacecraft from 1986 through 1994. Collection Organization The collection contains a chronological file folder list of ground support equipment Critical Design Reviews generated by contractor GE Astro Space Division under contract number 957444. The documents in this collection include Mars Observer Attitude & Articulations Control Subsystem (AACS), Command & Data Handling, Mechanics, Date Time Group (DTG) Pads, various drawings, MO data packages, Optical Decorders, Reaction Wheel Assembly, and the Gimbal Drive Electronics Unit. The GDE consisted of two redundant units within a common assembly. The GDE was devoted to either; 1) interfacing between the Control Interface Unit (CIT) and the Solar Array Gimbal Drive Assembly (SAGD), or 2) Antenna Gimbal Drive Assembly (AGDA). This included, receiving and decoding a 16 bit serial motor command word, providing optimization of stepper motor drive pulses for minimim power dissipation, providing status telemetry, and providing a hardware stop at the maximum limits of both antenna solar array rotation.
