This is a non-working example of an inertial navigation system for commercial aircraft. It was prepared by the Delco Division of General Motors, the manufacturer, for display purposes. Using a set of gyroscopes, accelerometers, and associated electronics, the system could determine an aircraft's position with no reference to the outside world (i.e. no radio beams or stellar sightings), assuming it is initialized properly. Such devices were in common use in trans-oceanic flights when they were out of range of ground-based radio navigation systems.
