Reliable and uninterrupted access to satellite navigation data is nowadays a key element for various branches of economy, security and safety. At the same time, GNSS systems are not 100% reliable and the issue of interference (both unintentional and intentional) affecting their operation is becoming more and more significant – especially in current geo-political situation. That is why a constant monitoring of GNSS signals and detection of interference is so important.

The main goal of this project is development of the concept, pilot  implementation and functional tests of national, Polish system for GNSS signals monitoring. Major functions of this system will include: 

• detection of interference and/or unavailability of GNSS signals on the territory of Poland,
• generating alarms regarding any instances where satellite navigation systems may work incorrectly, 
• real-time visualizations via a dedicated web service available to all interested users.   

For the purpose of the project this system will be referred to as: “Real-time GNSS Monitoring System for Poland” (RTGMS).

The system will feature two major components:

• Fixed – a network of GNSS monitoring stations operating non-stop and spread throughout Poland. They will utilize the existing infrastructure of the ASG-EUPOS network which will undergo a necessary expansion on a hardware and software level.
• Mobile – a GNSS measurement platform based on a van-type car, operating on an ad-hoc basis and conducting more in-depth and advanced analysis of interference incidents whenever necessary.
