Abstract :
Based on the observation of Mars probe with ground VLBI, the observation model including the position of Mars probe and connection parameters of reference systems is studied in this paper, and the estimable parameter sequence is determined. Then the adjustment method appropriate for rank defect in the matrix of normal equation coefficients is studied, the model parameters are calculated and their precisions are evaluated. Thirdly, the impact of accidental errors to the parameters is analyzed. The results are given at the end of the paper.
