Earth orientation parameters (EOP) are essential for the interconnection of different reference systems involved in Chang’E-1 (CE-1) lunar exploration, such as the Earth fixed reference system, celestial reference system and dynamical reference system. To improve the accuracy of predicted EOP values and to reduce their influence on the accuracy of CE-1 orbital parameters, a relativistic mathematical...
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...
