Background
Section titled “Background”This alarm is set when the navigation system doesn’t know about any docks. It blocks takeoff, because without information about which dock we are taking off from, navigation cannot perform its preflight checks.
The navigation system is informed about the docks involved in a mission when the mission is first received from the cloud. This alarm is expected to clear upon the reception of the first mission.
