Abstract: Based on the triple difference carrier phase observables,a GPS/INS integration (algorithm) for attitude determination is studied.The proposed integration system also contains a(cycle) slip detection algorithm,in which inertial information is utilized to detect cycle slip.Some computer simulations are performed to verify the proposed integration system.The results show that accurate and reliable navigation solution can be gained.
