One early stabilization technology is the anti-rolling gyro, or gyroscopic stabilization. The gyro is mounted in a gimbal. Unlike a directional gyro or heading indicator, a gyrocompass seeks north. However, the assembly of multiple optical components into a precision gyro instrument is costly. Above the mounting platform was the stabilization gyro. It was located on where Gyro Spin is now. "Thomas Washington" established geodetic positioning by (SATNAV) with Autolog Gyro and EM Log. The gyro was started when the torpedo was launched. Lockheed had studied ways to prevent unstable feedback from the gyro. The four Dummies were Crash, Crunch, Splice and Gyro. Fulton Gearloose is the son of Ratchet Gearloose and the father of Gyro Gearloose. In Conway polyhedron notation it can be seen as gT, a gyro tetrahedron. Man-At-Arms saved him with one of his latest inventions called the Gyro Machine. Another special was the NCB Gyro or Electrogyro Locomotive. HiPAP 102, two SeaPath 200, two Standard Gyro, and one fanbeam.
