分布式INS/GPS组合导航仿真器开发

在研制INS/GPS组合导航系统之前建立INS/GPS组合导航仿真器系统是节约研制成本和缩短开发周期的有效途径,利用多台计算机搭建分布式组合导航仿真器能够更逼真的对系统进行仿真。该仿真器由GPS仿真子系统、INS仿真子系统和INS/GPS组合导航仿真子系统三大部分组成,对该系统之间的硬件接口设计、算法和软件开发进行了论述,对比较难解决的系统同步问题提出了解决方法。最终的设计方案已成功的应用于某飞机仿真系统中。

Development of Distributed INS/GPS Integrated Navigation Simulator

Before developing an INS/GPS integrated navigation system, it is an efficient method to build an INS/GPS integrated navigation simulator to reduce cost and shorten period of development. Building a distributed simulator with multiple computers will be more close to the actual system. The simulator consists of GPS simulation subsystem, INS simulation subsystem and INS/GPS simulation subsystem. Hardware interface design, algorithm and software development of the simulator are discussed. Solving method for the scabrous problem of system synchronization is given as well. The final version of the designed scheme has been applied successfully in certain airplane simulation system.
