To increase the estimating precision of the exterior ballistic parameters in exterior ballistic measurement, a tracking point inconsistency correction method using non-telemetry and non-ballistic-programmer data was studied. The basic idea of tracking pointing inconsistency correction using GPS carrier phase was presented. The correction model taking double differences data of GPS carrier phase as parameters was built according to autual conditions of exterior ballistic measurement, and the corresponding data processing flow was designed. Simulation results show the feasibility of the model and flow method and indicate that the method can enhance the self-processing and self-evaluating ability in exterior ballistic measurement system.
