GNSS Antenna Calibration

Absolute GNSS Antenna Calibration

For special navigation applications the Institute of Geodesy offers the absolute calibration of GNSS receiver antennae. The calibration process focuses mainly on scientific aspects.

Robot-based Calibration

The development of the absolute field calibration of GNSS antennae (Hannover principle) was funded by the Ministry of Education and Research (BMBF) and the German Aerospace Center (DLR) in a project "Entwicklung und Erprobung eines Verfahrens zur hochpräzisen Kalibrierung von GPS-Antennenaufstellungen". This method was developed in cooperation with Geo++ (Gesellschaft für satellitengestützte und navigatorische Technologien mbH).

It is distinguished by a real time calibration process with a robotic arm to determine azimuth- and elevation-dependent phase center variations (PCC, PCV) of GNSS antennae with sub millimeter precision.

Services offered
  • Examination and analysis of GNSS reference and rover systems
  • Calibration and analysis of conventional GNSS receiver antennae
  • Calibration of special scientific GNSS sensors for satellite missions
  • Analysis of the antenna's near field effect on directionality
  • Advice and support for GNSS sensor technology

Services offered include analysis and evaluation as well as advice and support for general and specific questions about GNSS sensor technology.

Please be aware that there may be waiting times at the calibration facility due to ongoing scientific projects. Additionally, calibration is subject to weather conditions and outside temperatures, which may lead to temporary limitations.

We provide calibration services for carrier and code phases for all major Global Navigation Satellite Systems (GNSS), including GPS, Glonass, Galileo, and Beidou. We also support regional systems such as QZSS, IRNSS, and SBAS. Our precise calibration processes ensure high accuracy and reliability for your applications.

Calibration data are delivered in the international formats (antenna exchange format - ATX). The data are valid for the upper hemisphere (0°-90°) of the antenna as well as for all azimuth ranges and refer to the antenna reference point (ARP).
