The USB (YuanWang 2′s S band microwave unified TTC system) cannot complete tasks on the launch stage under the original operating mode because CE-1(Chang′E-1) satellite antenna covers the TTC station alternatively. Through improvting the current receiver, the new system operating mode is built,which extends the system function, and improves the capability of task completion.
