摘 要: | 卫星和地面之间的交流通过它们之间的数据通讯来实现。为了实现星地通讯,必须选定双方都要遵守的协议。考虑到星地通信的可靠性和效率,在选择通讯协议时需遵循实用且最简单的原则。参考CCSDS的相关建议和Ax.25协议,开发了一种星地链路层通信协议。纳星一号飞行试验的运行结果表明,该协议具有较高的数据传榆效率和良好的可靠性,可以满足微小卫星的实际通信要求。

Abstract: | The communication between ground stations and satellites is realized by the data transmission between them.To implement the communication the protocol must be selected.With a view to the reliability and efficiency of the communication between them,the prin- ciple of enough and simplicity are complied with,in this paper,According to the Ax.25 protocol and CCSDS information,a data link layer protocol is developed.The result of the NS-1 Satellite assembly integration test and flying test indicates that this protocol is reliable and effi- cient,so it can meet the application. |
