Abstract:	IT IS OBVIOUS that position fises obtained from the Navy Navigation Satellite System may be used t,o reset a pure inertial system on long missions where some form of resetting is desirable. This paper discusses a method of system integration whereby the doppler data is treated directly as the observable in a Kalman-filter reset scheme, and thus the intermediate step of computing a position fix is omitted. In the process, this method properly accounts for the vehicle velocity in any dynamical situation, which is a difficult problem when viewed from other approaches. Simulated computer results are presented.
