Abstract
In this paper, differential VLBI (ΔVLBI) model used for Chang´e-1 (CE-1) Transfer Orbit positioning is derived. Based on the model, error equation of observations is formed and coefficient matrix A is designed. Finally the influence of predicted accuracy of ERPs on CE-1 positioning accuracy is analyzed and some results are given.
