文章介绍了本所的研究成果《GNSS车载终端无线耦合校准方法研究》,讲述了校准方法、校准装置的工作原理和校准过程。经过分析论述,选择了科学、可行的验证方法——校准装置在特定状态下对定位、速度、里程参数采集回放并通过高精度接收机显示的数值与通过更高等级计量标准对对应相同状态下各种参数的测量标准值比较。实现了对GNSS车载终端无线耦合校准装置的整体计量性能测试和对GNSS车载终端无线耦合校准方法的验证。

This paper introduces the research of the GNSS vehicular terminal wireless coupling calibration method,and describes the calibration method,the working principle and the calibration process of the calibration device. Through the analysis and discussion,a scientific and feasible verification method is selected-the calibration device collects and replays the location,speed and mileage parameters in a specific state,and compares the values of the high precision receiver to the standard values of the various parameters under the same state through the higher grade measurement standard. The overall measurement performance test of the wireless coupling calibration device for GNSS vehicular terminals and the verification of wireless coupling calibration method for GNSS vehicular terminals are realized.
