摘　　要：传统舰船导航信息处理系统的丢包率过高,因此设计一种无线通信技术的舰船导航信息系统设计。在系统的硬件设计中,主要对容错联邦滤波器的结构进行设计,分别确定其中2个子滤波器的输入内容,使其独立工作,提高系统的容错性;软件设计中,设计数据库包括舰船信息、操作日志和错误记录,并对信息显示格式进行规范,优化故障检测算法,单独检测残差分量,简化运算,提高系统中的突变丢包检测灵敏度,至此完成了无线通信技术的舰船导航信息系统设计。通过仿真实验结果表明,设计的系统丢包率比现有系统降低36.6%。The packet loss rate of the traditional ship navigation information processing system is too high, so the design of a wireless communication technology of ship navigation information system design. In the hardware design of the system, the structure of the fault-tolerant federated filter is mainly designed, and the input contents of the two sub-filters are determined to work independently to improve the fault tolerance of the system. In software design, database design includes ship information, operation logs and error logging, and the information display format specifications, the optimized algorithm for fault detection, detection of residual component alone, simplify operation, improve the system of mutations in the packet loss detection sensitivity, thus completed the wireless communication technology of ship navigation information system design. The simulation results show that the packet loss rate of the designed system is 36.6% lower than that of the existing system.
