摘　　要：针对GNSS接收机检定费用较高、检定机构数量少且检定周期长的问题,该文提出了一种简易快速的GNSS接收机检定方法。该方法根据GNSS接收机天线相位中心的几何关系,通过自设简易检定场,利用相对定位法及超短基线法分别检测接收机天线的相位中心偏差和内部噪声水平,并编写了相应的计算程序对检测数据进行快速的处理。4次独立实验结果表明:该文实验方案具有较高的精度和可靠性,适用于快速对GNSS接收机天线相位中心偏差和内部噪声水平进行自检。In view of high cost of GNSS receiver calibration,low number of verification institutions and long cycle of verification,this paper put forward a simple and rapid verification method of GNSS receiver.According to the geometric relationship of GNSS receiver antenna phase center,this paper used relative positioning method and ultra short baseline inspection to detect the phase center variation and internal noise levels of the receiver antenna by establishing a simple verification place,and finally wrote out the relevant calculation program to process test data quickly.Four independent experiments showed that this experimental program had high-precision and reliability,and it was applicable for quickly self-testing of GNSS receiver antenna＇s phase center variation and internal noise levels.
