A Study on Antenna Relative Phase Center Variation

   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 calibration technique in anechoic chamber or the filed calibration technique with robot. Compared with above calibration techniques, the relative calibration technique are easy and operability. 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.
