Abstract
Apparatus and method for measuring specific force and angular rate of a moving body, particularly useful for a non-gyroscopic inertial measuring unit, comprises an orthogonal triad of rotating accelerometers, each producing an output signal "a", from which output signals are derived both (1) the angular rate vector .OMEGA. by multiplying the accelerometer output signal "a" by the function "SgnCos.omega.t" and integrating the resulting product over the cyclic period, and (2) the specific force vector F, by integrating the output signal "a" over the cyclic period, this processing of the accelerometer output signals substantially suppressing the unwanted components of these signals.
