BUZZ ALDRIN'S FLOWN APOLLO 11 LUNAR MODULE CHECKLIST. The AGS was the Abort Guidance System, a backup navigation system to the PGNS or Primary Guidance and Navigation System. Although there was no occasion to use the AGS for navigation, it was cross-checked with the PGNS prior to landing the Lunar Module to ensure that the two systems were in agreement. This was mainly a step to give the astronauts confidence in their systems.
