This web site provides Global Navigation Satellite System (GNSS) antenna calibrations for specific antenna types (antenna code + radome code). These calibrations are used by NGS for processing GNSS data in all its products and services. NGS offers complete, downloadable files of absolute antenna calibrations in both ANTEX and ANTINFO formats.

- An antenna calibration is the act of determining the point of reception of the GNSS carrier phase signals. Antenna calibrations are necessary to obtain the most precise and accurate GNSS positions possible. Antenna hardware such as the antenna elements and pre-amplifiers create signal phase advance and delay before the
As part of the IGS20 reference system, the absolute calibration values for many GNSS satellites and receiver antennas were updated with improved estimates or additional GNSS frequencies. In all, the calibrations for approximately 50 receiver antennas in the NGS database changed in November 2022.
22 de mar. de 2018 · The act of determining the phase centre corrections (PCC) for a GNSS antenna is called calibration. In this paper, we introduce a method to validate GNSS antenna calibration tables. The goal is to find the residual offsets due to imperfections in the antenna and its calibration table.
generate type mean calibrations for new antenna models entering the market, and to conduct individual calibrations for non-standard antenna installations or antennas which appear to deviate from the type mean. In this paper we describe NGS’s recently-developed absolute antenna calibration facility. After describing the
5 de jun. de 2014 · Set up the working standard of antenna and GNSS receiver of this calibration system on the forced-centering base on the pillars, rotate the direction mark on antenna to the north and fix it. Check the ends of signal cable are plugged in the antenna and receiver exactly.
