The Integration Algorithm of Space-Based and Ground-Based Tracking Data for Measurement Element

摘要：

　　In this article, an orbit determination method is introduced which is based on the integration of space-based and ground-based tracking data and the spline representation of trajectory.The feasibility of spline representation of trajectory is introduced and proved in the first;Subsequently, the problem of measurement element optimization and data weighting are solved, and the effect of measurement element on parameter estimation in linear model is analyzed and evaluated in detail;Finally theoretically analysis proves that the measuring element weighting can improve the parameters estimation precision in consideration of measuring element linearity and correlation.
