Evaluation of new Galileo services

Together with IABG GmbH, Prof. Thomas Pany, who holds the Professorship of Satellite Navigation, has acquired funding from the Bavarian space program for the GAP-AT project.

Navigation applications increasingly require high-precision and verified positioning solutions. For this purpose, two special signals are being developed for Galileo, which are currently (as of April 2022) being emitted as part of a kind of test operation. In order to evaluate and improve these signals and to define application-specific receiver architectures, the Professorship of Satellite Navigation and IABG GmbH has acquired funding for the GAP-AT project from the Bavarian space program.

The aim of the GAP-AT project is to develop a non-proprietary analysis tool for the new Galileo services Open Service Navigation Message Authentication (OS-NMA) and High Accuracy Service (HAS). The characteristics of this tool are:

  • Parallel processing of all Galileo and other GNSS frequencies (GPS, GLONASS, etc.)
  • High flexibility due to the use of an adaptable software receiver
  • Analysis of the new Galileo services (OS-NMA and HAS)
  • Intelligent analysis functions based on big data and machine learning
  • Future extendibility and adaptation to Galileo 2nd Generation

Precise (HAS) and verified position solutions (OS-NMA) can, for example, be used in road toll applications, since for one thing the vehicle is located on the lane and for another the positioning solution is also said to be resistant to position signal falsification. Other applications for high-precision services are automated agriculture and autonomous driving.

This project will help to promote the innovative power of the two Bavarian partners and the Free State of Bavaria at international level. At the same time, Bavaria’s position as a high-technology center for space and satellite technologies will be consolidated and new job opportunities will be created in the technology-oriented service sector.


Project period: 1 January 2022 to 31 December 2024
Funding by: Bavarian Space Programme

Coinciding with the GAP-AT project, the Munich Aerospace research group “GNSS RECEIVER ALGORITHMS FOR EXTENDED GALILEO SERVICES” deals with the same subject but has the clear aim of helping the two scholarship holders obtain their doctorates soon. In addition to IABG GmbH, Prof. Hugentobler from TUM is also involved in the research group. For more information, please visit the Munich Aerospace website >
