异常环境下GNSS接收机性能测试平台开发

Performance Test Platform Development of GNSS Receiver under Abnormal Conditions

摘要:

为了验证全球导航卫星系统(GNSS)接收机在电离层异常环境下的性能是否满足相应的技术规范要求,文章设计开发了GNSS接收机性能测试平台；该平台主要由信号仿真器、轨迹发生器、误差仿真模块、待测接收机以及性能测试模块组成,可以仿真不同电离层环境下的卫星信号,从而测定接收机在不同环境下的性能；详细介绍了误差仿真模块与测试模块的设计方案,并利用信号仿真器与接收机进行测试验证,证明了该平台的有效性。

Abstract:

In order to verify the receiver performance whether meet the requirements of the corresponding technical specification,especially in the Abnormal ionosphere environment,it developed a GNSS receiver performance test platform.The platform was mainly composed of signal simulator, error simulation module, the receiver under test and performance test module,it could simulate signals under different ionosphere environment to verify the receiver performance.It introduced the error simulation module and the performance test module in detail,and use them to prove the effectiveness of the platform.
