Abstract

Defines the requirements for a two-degree-of-freedom dynamically turned gyro (DTG) to be used as a sensor in a [strap-down, gimballed] [inertial navigation system, attitude reference unit,-] for use in [an aircraft, a missile, a spacecraft, -] application. The characteristics of the external capture electronics are considered where necessary to define gyro performance.
