摘要

NETPOS is a RTK network for governmental authorities of the Netherlands. The reference stations are equipped with Topcon PG-A1 antennas on a steel pipe mast. The influence of the mast on antenna phase centre variation appeared to be almost a centimetre. This is called the near field effect. The impact on rover positioning can be more that three times as large, resulting in an impact of more than 3 cm on the measured height. Calibration of the antenna including (the upper part of) the mast can eliminate this effect. This might be relevant for all GNSS users with a permanent reference station.
