APOLLO G&N SYSTEM EYEPIECE STOWAGE UNIT

Lidded plastic container, approximately 546 x 290 x 167 mm, metal hinges, two clasps to seal lid, bearing a AC Electronics tag on the back panel bearing the part no 2021255-011; serial no ACSK 2; cont. no NAS 9-497 and stating it was "Designed by MIT Instrumentation Lab."
Provenance: Purchased as surplus by a North American Rockwell engineer.

The Apollo Guidance and Navigation system was an integral part of the mission as it enabled inertial guidance and optical navigation. From the Apollo Guidance and Navigation System Study Guide, Block I (Series 100) G&N System Familiarization. N.p.: General Motors, February 1966: "The inertial guidance portion of the G&N system employs accelerometers mounted on a gyroscopically stabilized gimbal-mounted platform and a central data processing element. The inertial guidance system senses acceleration and attitude changes instantaneously and provides attitude control and thrust control signals to the stabilization and control system. The optical navigation portion of the G&N system employs a scanning telescope and a sextant to make sightings of celestial bodies and landmarks on the surface of the Moon and Earth. These sightings are used by the central data processing element to: a. Determine the spacecraft position and velocity. b. Establish proper alignment of the stable platform. A digital computer serves as the central processing element of the the G&N system."
The stowage case would be placed at the top of the Lower Equipment Bay above the Optics Panel in the Command Module.
