Apollo Guidance Computer carried two Apollo Guidance Computers (AGC), one each in the command module and the lunar module, with the exception of Apollo 8 which did not need a lunar module for its lunar orbit mission. The AGC in the command module was the center of its guidance, navigation and control (GNC) system. The AGC in the lunar module ran its Apollo PGNCS (primary guidance, navigation and control system), with the acronym pronounced as "pings". Each lunar mission had two additional computers: The AGC was designed at the MIT Instrumentation Laboratory under Charles Stark Draper, with hardware design led by Eldon C.
