INS

(Abbreviation for inertial navigation system.) A type of dead-reckoning navigational system, used on aircraft and other vehicles, which is based on the measurement of accelerations.

Accelerations are measured by devices such as gyroscopes, stabilized with respect to inertial space. Navigational information such as vehicle velocity, orientation, and position is determined from these measurements by computers or other instrumentation.
