GINTEC G50 GNSS Antenna Enhances Product Performance Through High-Precision Calibration

Geodetic and high-precision GNSS measurements require accurate knowledge of the reception characteristics of the GNSS antennas used, making antenna calibration essential. In pursuit of superior product accuracy, GINTEC entrusted the third-party organization GeoService GmbH to perform a professional calibration on its G50 antenna (certification name: GING50 NONE).

The calibration employed the robot-based Geo++® R-GNPCV real-time calibration system to obtain an absolute mean GNSS Phase Center Variation (PCV) type. The acquired absolute PCV data includes the following features: absolute 3D offsets, absolute PCV values, PCV from 0° to 90° elevation, elevation- and azimuth-dependent PCV, and is entirely free from multipath effects. The resulting PCV values are independent of the reference antenna used and enable complete modeling of the antenna’s reception characteristics. This is particularly important when combining different types of GNSS antennas or antennas with different orientations. Therefore, antennas calibrated with this method are highly suitable for All-In-View applications (e.g., reference stations).

The calibration results for the G50 antenna have been updated on the official NGS website. This initiative will help enhance the user experience with GINTEC’s high-precision products and reaffirms the company’s ongoing commitment to accuracy and professionalism.
