Data from three-way measurement is a kind of important observing data for deep space probes. By utilizing this data, this paper presents an algorithm to calculate the real-time position of deep space probes based on UKF (unscented Kalman Filter). The observing model and forecast method using the three-way measurement are given with the implementation method via dynamic modeling and non-dynamic modeling...
A real-time multi-mode robust filtering method is proposed for the large thrust and slow spin characteristics of the rocket above the flight stage. The rocket upper stage in the sliding section of the existence of slow spin characteristics, which will lead to ground measurement equipment tracking instability, poor measurement data quality. In order to solve this problem, the robustness theory and...
