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 the IGS14 reference system, in both ANTEX and ANTINFO formats. These can be found under the "Access Calibrations for All Antennas" menu above. If you need older products such as IGS08 calibrations or relative antenna calibrations, please contact
ngs.antcal @ noaa.gov. Note that IGb14 is supported by the calibrations provided on this website; see FAQ26 for details.
NGS also calibrates survey-grade antennas from qualified providers. See Policy and Procedures documents for details.
