[1] The star projector was movable in 3 directions while the capsule mockup and its pilots remained static.

The system was used in studies of manual control of spacecraft using "out the window" visual information both in orbit and in a launch abort scenario.

Vogeley in a paper presented at the American Society of Mechanical Engineers Winter 1966 meeting entitled "Piloted Space-Flight Simulation at Langley Research Center", the system was used to study Apollo launch-abort problems with a "horizon-to-horizon view of Florida as seen from about 100,000 feet."

The inflatable sphere enclosing the projector and fixed Gemini capsule mockup also displayed star images.

Navigational training of Gemini, Apollo, and some Space Shuttle astronauts was conducted at the Morehead Planetarium in Chapel Hill, North Carolina.
