研究基于无线网络的舰船实时导航数据采集与传输，满足舰船实时导航数据传输的多样性需求。利用GPS接收机、罗兰C接收机、多普勒计程仪等导航数据采集设备，采集舰船位置信息、航行速度等实时导航数据，所采集数据利用无线局域网传输至舰船导航系统。无线局域网编码处理舰船实时导航数据与通信信道，采用信道加密方法加密编码后数据，利用压缩感知算法重构加密后数据，完成无线局域网的数据接收；数据接收的反向操作即数据发送过程，通过数据接收与发送2个过程，实现舰船实时导航数据传输。实验结果表明，该方法利用平台罗经仪有效采集舰船首向角数据，不同类型的舰船实时导航数据传输均未存在丢包情况。
This paper studies the acquisition and transmission of ship real-time navigation data based on wireless network to meet the diverse requirements of ship real-time navigation data transmission. Navigation data acquisition devices such as GPS receiver, Roland C receiver and Doppler log are used to collect real-time navigation data such as ship position information and sailing speed. The collected data are transmitted to ship navigation system by wireless LAN. The real-time navigation data and communication channel are encoded by wireless LAN. The channel encryption method is used to encrypt the encoded data, and the compressed sensing algorithm is used to reconstruct the encrypted data to complete the wireless LAN data reception. The reverse operation of data receiving is the process of data sending. Through the two processes of data receiving and sending, real-time navigation data transmission is realized. Experimental results show that the proposed method can effectively collect ship heading angle data with the platform gyroscope, and there is no packet loss in real-time navigation data transmission of different types of ships.
