Developing Inertial Navigation
Innovations
The components pictured here are just part of the Ship’s Inertial Navigation System (SINS) used to steer submarines such as the USS Alabama.
A modified IBM Selectric typewriter connected to a control unit provided input and output for the system computers.
Model of Ship’s Inertial Navigation (SINS) stable platform made by Charles Stark Draper Laboratories. This platform is isolated from the movements of the ship, allowing those movements to be measured.
