Well, the site says it's a "CSM Guidance Computer Compensation Module"; that should be some kind of clue to its origins. |

The "OPTICS" on the label indicates that this module was part of the optics subsystem of the PGNCS, which on the CSM included the sextant and the scanning telescope. The "800 CPS" means 800 Hz (Cycles Per Second), which indicates this module was on the analog side of the loop. The Apollo Guidance Computer (AGC) sent digital commands to the optics that were converted to 800 Hz analog signals by the Coupling Data Unit (CDU), which then went to the motor drive assembly (MDA) on the optics. The shaft and trunnion angle resolvers on the optics in turn sent analog signals back to the CDU, which converted them to digital and relayed them to the AGC. Since the CDU A-D and D-A channels were not dedicated to the optics, I would guess that this module was installed on the optics side, not at the CDU. Beyond that, I can't really guess what this module did ("compensated" for something, but what?), or where it fit into the overall loop. The schematics I have aren't detailed enough to include it. |

There's a comments form just below the description. While that's a good article, from a site run by a former s.s.* regular (hi rk!), I don't think it will provide any clues regarding the compensation module. The article is about the LM guidance computer, not the one on the CM. While the computers are identical, the optics subsystems were very different on the two vehicles. Unlike the SXT/SCT on the CM which could be pointed by the computer, the LM had the Alignment Optical Telescope, which was pointed manually by the crew. Therefore the AOT had no 800 Hz interface with the CDU, and would have had no need for an 800 Hz compensation module. |
