Abstract—In this paper, we extend prior research on Interacting Multiple Model (IMM) Kalman filtering for GPS carrier phase estimation through wideband interference from static to moving receivers. In preparation, we develop a vibration dynamic model for the clock and a carrier-to-noise ratio estimator applicable in interference condition. We couple an Inertial Measurement Unit (IMU) with the GPS receiver to provide inertial aiding for user dynamics.
Keywords—GPS carrier phase estimation, interference mitigation, IMU inertial aiding
