National Institute of Telecommunications

Work on the RTGMS project will be conducted by the Wireless Systems and Networks Department of the National Institute of Telecommunications in Gdańsk in cooperation with the Polish Head Office of Geodesy and Cartography.

The main objective of the RTGMS project is to develop a concept, pilot implementation, and conduct functional tests of a nationwide GNSS (Global Navigation Satellite Systems) signal monitoring system. Key functions of the system will include:

• Detecting interference and/or unavailability of GNSS signals across Poland,
• Generating alerts for cases where satellite navigation systems may function improperly,
• Real-time data visualization via an online service accessible to all interested users.

The system will consist of two main components:

• Stationary Component – a network of continuously operating GNSS monitoring stations deployed throughout Poland. These stations will use the existing ASG-EUPOS network infrastructure, which will be upgraded both in terms of hardware and software.
• Mobile Component – a GNSS measurement platform installed on a vehicle, operating in ad-hoc mode. This platform will conduct more detailed and advanced analyses of interference incidents when necessary.

Access to reliable satellite navigation data is currently essential for various sectors of the economy, as well as for national security and defense. Simultaneously, GNSS systems are not fully reliable, and the issue of interference (both accidental and intentional) affecting their operation is becoming increasingly significant, particularly in the context of the current geopolitical situation. Therefore, continuous GNSS signal monitoring and interference detection are crucial.

The RTGMS project aims to enhance the safety and reliability of satellite navigation services in Poland by creating a comprehensive GNSS signal monitoring system that will respond to interference in real-time and provide users with up-to-date information on the navigation system's status.
