【摘要】：为了将地面IP网络技术应用于航天器内部设备间的数据通信,并实现与地面站的互连,根据航天器与地面站之间通信链路的特点,提出一种IP网络协议体系结构,实现天地一体化网络通信。在航天器上采用以太网协议完成内部网络数据交换,配置天地网关设备完成与地面测控通信网络之间的IP包交换;地面测控通信网络采用计算机IP网络,并配套相应的天地网关设备,完成与航天器的IP包交换。根据航天器数据的特点,提出一种速率控制策略,优先传输控制数据,控制图像话音数据周期平均速率,控制试验数据IP包平均速率。地面仿真试验及实际系统测试结果表明:文章提出的航天器IP网络设计,适应航天器与地面站的通信链路,可直接应用于高、中、低轨航天器的天地一化网络通信,也可为后续月球、火星等探测任务提供参考。
[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.
