摘　　要：为了拓展北斗卫星导航系统短报文通信在海战场指挥控制领域中的应用,针对北斗短报文通信信道窄、可靠性差以及通信频次受限等问题,对北斗短报文传输协议进行了研究。借鉴计算机网络中传输控制协议的思想,设计了一种定时反馈重传机制加数据冗余编码的长报文传输协议,提高了数据传输的可靠性。进行了仿真试验,表明该方法可以在一定范围内解决丢包恢复问题,提高信息的传输成功率和抗误码性能。In order to expand the application of short message communication technology based on Beidou satellite navigation system in the field of command and control,meanwhile in view of the narrow communication channel and limited communication frequency of Beidou,that the short message transmission protocol is studied.Considering the idea of transmission control protocol in the computer network,a data redundancy coding transmission protocol based on re transmission mechanism is designed,the reliability of data transmission is improved.Finally,the simulation experiment is carried out,the simulation results show that this method can solve the problem of packet loss,and improve the success rate and error resilience of information transmission.
