It will be during this pass that we will have the translunar injection burn.

這一回將飛船射入軌道

Since different orbit has different orbit characteristic, this paper analyses the accuracy of orbit determination for Translunar orbit and Mission orbit separtely.

Increasing observation accuracyand reducing the error of the measuring ship will improve the accuracy of orbit determination during Translunar orbit phase,and the reduced dynamic method and improvement of lunar gravity accuracy will benefit the accuracy of orbit determination during Misson Orbit phase.

This paper focus as on the Accuracy Analysis of orbit determination for the on-going Chinese lunar exploration mission 'Chang Er 1', using the joint tracking network of USB and VLBI with real network geographic distribution scenario and considering both systematic and stochastic measurement noise. The whole flight orbit of the Charng Er 1' includes Phasing orbit, Translunar orbit and Mission orbit.
