摘要
在精密定位中,GNSS接收机天线相位中心变化是必须进行改正的影响因素。目前成熟的微波暗室法和自动机器人法,对于一般用户而言,不具备相关实验条件,而野外相对法相对简单、易操作。为此,本文利用相对检测法,对GNSS接收机天线相位中心变化进行检测。实例表明,此方法可获得精度优于±3mm的检测结果,因此可利用此方法对其他类型天线PCV值进行检测,也可借鉴此方法对北斗接收机天线相位中心变化进行检测。同时论文分析了影响检测精度,提出了有益改进建议。
In high precise positioning, GNSS receiver antenna phase center variation is an error must be corrected. For normal users, they have no experimental equipment for the cali- bration technique in anechoic chamber or the filed calibration technique with robot. Com- pared with above calibration techniques, the relative calibration technique are easy and opera- bility. This paper used this calibration technique to calibrate the GNSS receiver antenna PCV. The results showed that the accuracies of this technique is 3mm, so this technique could be used for calibrating another GNSS receiver antenna and BDS receiver antenna. We analysis the influence factors for detection precision, and present some useful conclusions.
