Abstract:	INERTIAL navigation and Doppler navigation are two recent developments of extreme importance, particularly in military applications. Each is a method of determining the position and velocity of a moving vehicle, and each has limitations resulting from the components which make up the system. The characteristics of various forms of combined navigation systems have been investigated. As well as being of practical importance, this is an interesting example of the general problem of determining the optimum combination of two measurements of the same quantity. The methods of Wiener filter theory can be applied, although the inherent presence of transfer functions corresponding to undamped systems necessitates care in using this theory. In certain cases, particularly where the greatest accuracy is desired, the resulting system offers distinct advantages over either Doppler or inertial separately; while in other cases the additional complication of two systems does not appear justified.
