Research on STK real-time control in the distributed simulation

提出了基于STK-RTI的分布式仿真架构,给出了具体的时间同步策略;然后介绍了基于STK/Connect模块的网络通信原理和编程实现方法;其次给出了两种实时驱动卫星工具包(STK)的方式“SetTime”方式和“Real-Time/X-Real-Time”方式,进而阐明了两种驱动方式的原理和优缺点;最后针对“Real-Time/X-Real-Time”方式给出了一种更加高效、精确的实时获得STK时间的算法。

The application of STK in the distributed simulation becomes the focus of aerospace simulation. At first, the structure of distributed simulation based on STK-RTI was proposed, and the time synchronization scheme was given. Then, the principle of network communication based on the STK/Connect module was introduced and its realization of programming. At the same time, the two schemes on driving STK in real time--SetTime scheme and Real-Time /X-Real-Time-scheme were proposed, and the principle of the two driving schemes was stated as well as their advantages and disadvantages. At last, based on the Real-Time/X-Real-Time scheme, an algorithm which can get the time of STK more efficiently and more exactly in real time was proposed.
