GPS接收机室内检定方法的初步探讨

Preliminary discussion on indoor verification method of GPS receiver

GPS接收机室内检定方法是采用卫星导航信号采集回放仪、扼流圈天线、微波暗室搭建的室内GPS接收机检定装置,使用该装置在野外实际标准点位采集卫星数据,然后在微波暗室摆放接收机,并对接收机回放数据野外采集数据,最后使用高精度数据处理软件解算数据,完成室内GPS接受机精度的检定。本方法克服了现在检定方法全野外数据采集受天气影响的弊端,可以在一定程度上节省人力物力。

The indoor calibration method of GPS receiver is an indoor GPS receiver verification device built by satellite navigation signal acquisition and playback instrument, choke coil antenna and microwave darkroom. The device is used to collect satellite data in the field at the actual standard point, and then in the microwave darkroom. The receiver is placed and the data is collected in the field by the receiver playback data. Finally, the high-precision data processing software is used to solve the data, and the accuracy of the indoor gps receiver is verified. The method overcomes the drawbacks of the current verification method that the data collection in the field is affected by the weather, and can save manpower and material resources to a certain extent.
