An aircraft operating in a gravitational field and having conventional sensors for measuring true air speed (sensors 10, 11), angles of incidence and yaw (sensors 13, 12), rotation about x, y and z axes and acceleration therealong (sensors 14, 15, 16) is provided with means for calculating the inert

An aircraft operating in a gravitational field and having conventional sensors for measuring true air speed (sensors 10, 11), angles of incidence and yaw (sensors 13, 12), rotation about x, y and z axes and acceleration therealong (sensors 14, 15, 16) is provided with means for calculating the inertial component of the acceleration from data concerning the true air speed, heading and rotation of the aircraft obtained from the sensors, and means for comparing the inertial component with the total acceleration sensed, thereby to deduce the orientation of the gravitational component and hence obtain an estimate of the pitch and bank angles of the aircraft.

A method of determining the attitude of a body operating in a gravitational field comprising: measuring the total acceleration acting on the body in relation to a coordinate system fixed with respect to said body; calculating the total inertial component of the total acceleration in relation to said

A method of determining the attitude of a body operating in a gravitational field comprising: measuring the total acceleration acting on the body in relation to a coordinate system fixed with respect to said body; calculating the total inertial component of the total acceleration in relation to said coordinate system; comparing said measured total acceleration with said total inertial component, thereby to generate data representative of the orientation of the gravitational component of acceleration in relation to said coordinate system; and processing said data to determine the attitude of said body.
