[Abstract]:In order to apply the ground IP network technology to the data communication between the internal equipments of the spacecraft and to realize the interconnection with the earth station, according to the characteristics of the communication link between the spacecraft and the earth station, a IP network protocol architecture is proposed. Realize the integration of heaven and earth network communication. The Ethernet protocol is used to complete the data exchange in the internal network on the spacecraft, and the IP packet exchange between the ground measurement and control communication network and the earth gateway equipment is configured.; the ground measurement and control communication network uses the computer IP network. And matching the corresponding heaven and earth gateway equipment to complete the IP packet exchange with the spacecraft. According to the characteristics of spacecraft data, a rate control strategy is proposed, which preferentially transmits control data, controls the average rate of image voice data cycle, and controls the IP packet average rate of experimental data. The results of ground simulation and actual system test show that the proposed design of spacecraft IP network is suitable for the communication link between spacecraft and earth station, and can be directly applied to the network communication of high, middle and low orbit spacecraft. It can also be used as a reference for future missions such as the moon and Mars.
