University of Greifswald: New backup system for GPS security!

Greifswald, Deutschland - in Greifswald is currently exciting! The University of Greifswald is at the head of an ambitious research project that could revolutionize the satellite -based navigation. With the name "Air-Mopsy", researchers develop a backup system for GNSS technology (global navigation satellite system) in order to ensure reliable position and time data even with disorders of GPS signals. According to [NDR] (https://www.ndr.de/nachrichten/mecklenburg-vorpommern/universitaet-greifswald-gps-gps-Backup-System-System-System-System-Mvregiogswald-206.html), the project comes at the right time in view of the frequent signal disorders.

The project manager, Professor Dr. Christian von Savigny emphasizes how important such a backup system is for the security and accuracy of navigation in the region. In addition to the University of Greifswald, four other research institutes are involved in the project, which promotes interdisciplinary cooperation and strengthens the region's innovative strength. The total financing of five million euros comes from the state excellence initiative "Application -oriented excellence research", which recently announced its results [University Greifswald] (https://www.uni-greifswald.de/en/forschung/nachrichten-aus-der-forschung/navigation-safety-state-excellence-project-for-for-independent- back-ystem-ystem-system-ystem-system-system-ystem-yste-system-system-yste-ysteit-ysteit-

focus on atmospheric influences

The Air Mopsy project is particularly devoted to the influence of the atmosphere on the R-mode positioning system. It is examined how variability in the middle atmosphere influence the spread of radio waves in order to improve the accuracy of backup systems. This topic has special relevance, since artificial disorders have increased in the GNSS signals in the Baltic Sea area and can thus also endanger the safety of applications.

The prospective solutions could not only be important for the Mecklenburg-Western Pomerania region, but also for all of Germany and beyond. A current initiative of the Federal Office for Cartography and Geodesy (BKG) has also launched a central service for satellite -based position determination. This service promises to enable position provisions with an accuracy of a few centimeters and has been in regular operation since January 2025 (https://www.bkg.bund.de/de/produkte-undstienst/positioningdienst.html).

A look into the future

The project in Greifswald is part of a number of five funded cooperation projects that deal with important social issues. The importance of these research approaches was also emphasized by the Minister of Science, who emphasized the role of applied research for the competitiveness of Mecklenburg-Western Pomerania. So for the future we can hope for exciting developments that could not only make our navigation system safer, but also overall smarter.

In a time when technologies are constantly evolving and also increasing challenges due to disorders in data transfers, Greifswald with Air-Mopsy impressively shows that the region is ready to develop and apply innovative solutions. This commitment to research and development could bring Mecklenburg-Western Pomerania to the front.
