In this paper, a relativistic differential VLBI (Δ VLBI) mathematical model for Chang'e-1(CE-1) Transfer orbit is derived Based on the model, Δ VLBI time delay observations are formed by differencing CE-1 time delay observations with a simulated radio source time delay observations. Then the error equation of observations is formed and the unknown parameters including orbit of CE-1 and Earth Orientation Parameters (EOPs) are calculated under least squares adjustment Finally, the accuracy of each parameter is given.
