#TheApolloGuidanceComputer was built to navigate and guide the #Apollo astronauts to the moon. The #AGC and the inertial measurement unit (IMU) told astronauts where they were. The IMU contained gyroscopes and accelerometers. The IMU was calibrated using an onboard telescope and sextant. The AGC also controlled the engines and reaction control thrusters. The astronauts talked to the computer using verb and noun commands on DSKY (display and keyboard). The computer itself was make of core memory. The fixed memory was woven core rope memory. This is where the programs, constants, star charts, and landmark charts were woven and saved for each flight. The logic unit was make of integrated circuits (dual NOR gates). The computer could only run one job at a time. The executive determined what jobs to prioritize and run. The computer could restart programs, put them to sleep, and had very basic error checking. It was designed by MIT's Instrumentation Lab and built by Raytheon. There was one for the command service module and one for the lunar excursion module. New versions were built for every flight. • Many of the images and video came from this site. It is a great site to explore.
