Apollo 2 Command Module G&N Indicator Control Panel

Summary

[edit]
Description
English: Apollo 2 Command Module G&N Indicator Control Panel: The “Tracker Power” toggle switch to the lower left was unique to and identifies this panel as either intended for or originating from Apollo Command Module 014; this spacecraft was slated to fly as Apollo 2 but dismantled after the Apollo 1 fire.

The G&N system was used for Guidance and Navigation, developed by the MIT Instrumentation Lab, under the very first Apollo contract. The optical unit had a precision sextant (SXT) fixed to the IMU frame that could measure angles between stars and Earth or Moon landmarks or the horizon. The little joystick controls two axes of the optical system. The "Mark" button (top right) sends a signal to the Guidance Computer (AGC) to record time and optics and gimbal angles (MIT video, 1965). The Attitude impulse hand control supplies signals to the thrusters to position the spacecraft in attitude. And the main controls have metal bars to assist in holding on while navigating in zero-g.

This panel was directly below the optical sextant and scanning telescope, with controls for the IMU and gyroscopes as well. The adjacent joystick allowed the astronaut to make small attitude adjustments via short bursts from the array of small engines outside the spacecraft (see configuration below).

Lower Equipment Bay (LEB) Control Panel 105 assembly that comprised part of the Guidance and Navigation interface, 23.5 x 13, bearing a NASA parts label on the reverse of the panel reading, “Apollo G&N System, G&N Indicator Control Panel Assembly, Part No. 1014664-021, Serial No. ACSK 3, Cont. No. NAS 9-497.” The panel is stenciled “Qual Test” in several areas in yellow text. Sections of the front of the panel are labeled “Optics,” “Attitude Impulse,” “Map and Data Viewer,” and “IMU Temp Mode,” all with various buttons, switches, and controls; an area to the upper left is inset with a joystick control.

The bottom right controls are for the IMU, with gain control for the IRIG (Inertial Reference Integrating Gyroscope) and PIPA (Pulsed Integrating Pendulous Accelerometer).
