    14 de ene. de 2021 · Recently, NGS added the ability to compute absolute calibrations using a robotic arm as the antenna test platform. This advance enables robust, full-azimuth calibrations for multiple GNSS, beyond simply GPS L1 and L2.This webinar introduces key concepts of antenna calibrations and reviews the history of calibrations at NGS.

    An antenna calibration is the act of determining the point of reception of the Global Navigation Satellite System (GNSS) carrier phase signals. Antenna hardware such as the antenna elements and pre-amplifiers create signal phase advance and delay before passing the signal to the receiver.

    22 de mar. de 2018 · 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. Nowadays, accepted calibration methods include field robot calibration and calibration in an anechoic chamber.
