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) with integrated tactical communications, navigation and positioning and intranet recognition. Due to its work in the Lx (960-1215 MHz) band, it is unable to complete the over-the-horizon real-time transmission of information, which limits its application in the over-the-horizon maneuver. TIS gateway is to achieve TIS information and allegations of information beyond the horizon real-time transmission of key equipment. This paper constructs a TIS gateway based on VxWorks real-time operating system. By using VxWorks’s rich and standard sockets programming interface and multitasking mechanism, the data link with synchronous satellite as the relay enables TIS information and allegation of information over-the-horizon Real-time transmission, to solve the real-time transmission of information beyond the horizon.
