GIREKO – GNSS Interference Map Austria

Due to the widespread use of GNSS, it is necessary to have comprehensive information about occurring interferences in the GNSS frequency band.

Nowadays, GNSS (Global Navigation Satellite System) is more and more used by providers of critical infrastructures, e.g. for time synchronisation of finance transactions, in telecommunication networks, for power supply systems, aviation, as well as for organizations like the military. In the previous research projects TACTIC and Be-Aware, JR and IGASPIN together could impressively show how vulnerable GNSS receivers are due to jamming and spoofing, and that these attacks are a serious threat. 

This is the starting point for this activity called GIREKO. Today, worldwide, only a few monitoring stations exist observing unintentional or intentional GNSS interference. Ideally, this information should be collected area-wide to be able to inform GNSS users as needed. Current existing (research) approaches for interference detection are either very expensive solutions (several thousand euros, very reliable) or crowdsourcing approaches with Android smartphones (reliable by an increased number of users). 

Within this proposed project, a cost-efficient SDR based technology for interference detection and characterisation shall be found that allows supporting to fill a GNSS interference map for Austria with trustful information. This technology will consist of hardware and software components and shall combine the advantages of existing high-cost (reliable, capability of interference characterisation) and low-cost (affordable) solutions. Research will be done to find appropriate sensors and data recording approaches to minimize hardware costs for an interference sensor node. The interference detection and characterisation therefore will be based on novel artificial intelligence approaches. The detected interference events afterwards will be visualized in a GNSS interference map Austria. This map furthermore enables to warn GNSS users like provider of critical infrastructure if needed. Another important research topic of this project is the efficient warning process. For an efficient distribution of information about interference events, the project shall also discuss with the stakeholders how much knowledge about GNSS interference is available and how a concept about advance warning can be implemented to gain a maximum benefit for all parties. This information will be collected either by interviews and practical exercises where the advantages and environmental conditions of a warning system will be examined practically.
