摘　　要：The method of integrated data processing for GPS and INS(inertial navigation system) field test over the Rocky Mountains using the adaptive Kalman filtering technique is presented. On the basis of the known GPS outputs and the offset of GPS and INS, state equations and observations are designed to perform the calculation and improve the navigation accuracy. An example shows that with the method the reliable navigation parameters have been obtained.The method of integrated data processing for GPS and INS（inertial navigation system） field test over the Rocky Mountains using the adaptive Kalman filtering technique is presented.
