It is one of the most important parts in accuracy analysis for vehicles launched on moving base, to realize the initial error separation utilizing the telemetric data and exterior data obtained in initial phase. Starting with the initial error mechanism analysis, a formula of the apparent velocity difference between telemetric data and exterior data is deduced. Then the relationship between the platform inertial coordinate system and the launching coordinate system is analyzed, and the linear model of initial error separation in apparent position region is established. Through the initial error separation simulation using the data generated by the ballistic simulate platform, the accuracy and feasibility of both the model and the estimating method are proved.
