The Apollo Command Module (CM) and Lunar Module (LM), were each equipped with a version of PGNCS. PGNCS, and specifically its computer, were also the command center for all system inputs from the LM, including the Kollsman Instrument built Alignment Optical Telescope, the radar system, the manual Translation and Rotation device inputs by the astronauts as well as other inputs from the LM systems. PGNCS was developed by the MIT Instrumentation Laboratory. The Prime Contractor for PGNCS and manufacturer of the Inertial Measurement Unit, IMU was the Delco Division of General Motors. Development was under the direction of Charles Stark Draper and MIT Draper Labs and consisted of the following components:an Inertial Measurement Unit (IMU)the Apollo Guidance Computerresolvers to convert inertial platform angles to signals usable for servo controlan optical unita mechanical frame, called the Navigation Base (or Navbase), to rigidly connect the optical device and, in the LM, the rendezvous radar to the IMUthe AGC software"@en }
