Mechanization of an inertial navigation system with an arbitrary azimuth and vertical location
Abstract
A platform with a number of inertial sensors is considered. The instruments include three accelerometers and three gyroscopes with one degree of freedom. A special support system insulates the platform from the movements of the aircraft. An earthrelated reference system is considered and the mathematical relations for the systems operations are presented, taking into account nine equations which provide at each moment information regarding the matrix of the direction cosines. The calculation procedure with respect to the various computational operations involved is illustrated with the aid of a graphical representation. The derivation of a number of important mathematical relations is shown in detail.
