| Abstract: | DDN system accomplishes data transmission and exchange in astronautic mission, including tracking and control information, command and dispatching, daily communications, etc. In this paper, we analyze the abnormal performance of DDN high speed data transmission between node and command center in an important mission. The preliminary conclusion is obtained by analyzing and deducing the problems occurring in check and test trials, and we propose the corresponding measures and method for these problems. |
