Inertial systems have been used for about fifteen years to determine the anomalous gravity vector at discrete points using zero velocity update measurements at vehicle stops. This paper discusses a kinematic method of determining continuous geoid profiles from a combination of INS and GPS measurements. The major error sources, namely gyro drift, accelerometer bias variation, and GPS noise are modelled separately and their effect on the resulting relative geoid is studied.
