A method of combining orbit by M estimation and dynamic smoothing
Feng Lai · 2010
To get combinition orbit from muti-Analysis Center solution, a new method based on robust M estimation and dynamics smoothing is presented. This method makes combined orbit more reasonable by utilizing decreasing weight of singular data based on M estimation. The discrete orbit can be smoothed with dynamic information to avoid the uncontinuous orbit. In order to prove the correctness of methods, the IGS orbit and the lasering data are used as external check standards, and the results show that the combination orbit is consistent with the IGS orbit on precision and consistency.
