Abstract
The ultra-tightly coupled GPS/INS integration system is known to be a method to provide an accurate navigation solution and high anti-jamming capability dynamic environment. Since the correlator outputs of the GPS receiver are measurements of the integration Kalman filter in the method, a different hardware configuration from the loosely and/or tightly-coupled integration method should be required. A COTS(Commercial Off-The-Shelf) GPS signal processing chipset based ultra-tightly coupled GPS/INS integration system design method is proposed.
