The real-time system put forward here is a soft real-time system based on Windows NT. Preemptive multitasking mechanism is used on NT, in this way, the beyond-visual-range and real-time transmission of the TIS and command/control information can be realized via data link relayed by synchronous satellite.

实现的实时系统是一个基于Windows NT的弱实时系统,它通过在NT上采用多任务抢占机制以及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。
