摘　　要：本文以树莓派嵌入式系统板作为运算处理核心,构建了软件无线电体制的GPS信号模拟器。通过使用Open MP并行计算加速技术,提高了基带信号的产生效率,实现了12通道基带GPS信号的实时产生和传输;通过使用Web动态交互技术,实现了跨平台的设备远程控制管理。并且利用北斗星通天璇C200-AT导航接收机对模拟器输出信号进行了测试,测试结果验证了系统的功能和输出信号的有效性。This paper constructs the GPS signal simulator under the software defined radio architecture by using the Raspberry-Pi embedded system board as the core of operation processing. With Open MP parallel compute acceleration technology, the generating efficiency of baseband signal is improved, the real-time generation and transmission of 12-channel baseband GPS signal is realized, and the remote control management of this simulator is realized through the use of web dynamic interaction technology. And using the C200-AT navigation receiver to test the output signal of the simulator, the test results verify the function of the simulator and the validity of the output signal.
