This system contained a set of gyroscopes that assisted in the guidance, navigation and control of the Gemini spacecraft. It was installed and flown on the Gemini 3 mission on March 23, 1965, piloted by Virgil Grissom and John Young.

A major difference between Project Gemini and its predecessor, Project Mercury, was its goal of changing the spacecraft's orbit and rendezvousing with other spacecraft. The Gemini spacecraft therefore required an on-board guidance capability that was much greater than Mercury's. This inertial system provided a stable platform, which provided information to an on-board digital computer. This information enabled the Gemini astronauts to maneuver their craft in space.

Transferred from NASA to the National Air and Space Museum in 1972.
