天地一体化网络中的航天器IP网络设计
Spacecraft IP Network Design Used in Integrated Space-ground Network
摘要
Abstract
In order to use IP (internet protocol) technology to transmit information between spacecraft equipments and to link spacecraft and ground stations,an IP network protocol architecture is proposed based on the characteristics of the links between spacecraft and ground stations to realize integrated space-ground network communications.The Ethernet is used to exchange data between spacecraft equipments,and a space gateway is used to exchange IP packages with ground stations.IP network is used in ground stations,and a ground gateway is used to exchange IP packages with spacecraft.A rate control strategy based on the characteristics of spacecraft data is presented.The control data is transmitted immediately,the video and audio data rate is controlled based on periods,and the experimental data rate is controlled based on IP package.The results of ground simulation and system test show that the spacecraft IP network design mentioned above is suitable for the space and ground station communications links,and can be used in the integrated space-ground network of GEO,MEO or LEO spacecraft and as a reference for the moon and Mars missions.关键词
