The wide applications of RLG in vehicle-borne navigation system are indicated. Discrete KF(Kalman Filter) algorithms for SINS/DR integrated navigation system,including state equations and measurement equations,are introduced where SINS error equations are Continuous and DR error equations are discrete.Finally the simulation result shows that the position errors of SINS/DR integrated navigation system are prior to that of SINS and DR system respectively,when some error source can be estimated and be compensated in the integrated navigation system.
