摘要 首先介绍了全球定位系统(GPS)的工作原理;然后给出了利用多普勒频偏原理测量GPS接收机天线位移的方法;最后通过现场实验,对比GPS接收机天线的运动轨迹曲线和红球的运动轨迹曲线,验证了该测量位移方法的可行性。 The working principle of Global Positioning System is introduced firstly. Then, the method based on Doppler frequency shift principle for measuring a GPS receiver antenna's displacement is proposed. The GPS receiver antenna's trajectory curve and the red bali's trajectory curve are compared through the field experiment finally, which verifies the feasibility of the method.
