摘　　要：战术信息系统(TIS)具有集成的战术通信、导航定位和网内识别功能。由于其工作在Lx(960-1215 MHz)频段,无法完成信息的超视距实时传输,限制了其在超视距机动作战中的应用。TIS网关是实现TIS信息和指控信息的超视距实时传输的关键设备。该文构建了一个基于VxWorks实时操作系统的TIS网关,利用VxWorks丰富而标准的sockets编程接口和多任务机制,通过同步卫星为中继的数据链路,实现了TIS信息和指控信息的超视距实时传输,解决了信息的超视距实时传输问题。Tactical information system （TIS） has the communications, navigation, and identification functions. It uses pulsed transmissions in the 960-1215 MHz （Lx band） frequency band, so unable to realize the real-time and BLOS （beyond line of sight） transmission of information, The application of it in BLOS and mobile operation is limited, TIS gateway is the key equipment to realize the real-time and BLOS transmission of the TIS, command and control information. Based on real-time operating system VxWorks, the article designs a TIS gateway with the use of the socket programming interface and multitask mechanism of VxWorks. In this way, the BLOS and real-time transmission of the TIS, command and control information can be realized via data link relayed by synchronous satellite.
