多模卫星信号仿真器的软件设计

The Software Design for Multi-mode Satellitic Signal Simulator

本文以多模卫星信号仿真器的研制为背景,对GPS/GLONASS/BD三模仿真器上位机软件设计进行了详细的说明,介绍了仿真器软件开发的总体方案和关键模块,重点对用户界面的设计、上位机与下位机之间的数据通信、多线程的使用进行了详细论述。最后通过实际硬件平台和商用接收机对仿真器进行实验了验证。结果表明,该仿真器产生出的三个导航系统的卫星信号能够被接收机正确接收,验证了仿真器软件的正确性和实用性。

this paper presented the design for the software of the satelhic signal simulator on the background of the Research of GPS/ GLONASS/BD satelltic signal simulator, the software＇s total framework and key modules are introduced, with the emphasis on the user interface design, the communication between the upper computer and the lower hardware, the multi-thread using. At last, the simulator＇s effects were tested by the actual hardware platform and the mature commercial receiver. The test results show that the satellitic signal which generated by the simulator can be received correctly by receiver, the design of the software is useful and correct.
