National Institute of Telecommunications at the Geodetic and Cartographic Service Conference
06.05.2026
On May the 6th, the Geodetic and Cartographic Service Conference entitled "Geodesy - More Than Maps and Measurements. GNSS, Public Security and Technologies for Industry” took place in Ożarów Mazowiecki. The event was organized by the Head Office of Geodesy and Cartography (GUGiK). Representatives of public administration, academia, and the geodetic industry from across Poland attended the conference. The program focused on modern applications of satellite technologies, the security of critical infrastructure, and the growing importance of GNSS systems for the economy and public administration.
The National Institute of Telecommunications was represented by Prof. Mariusz Figurski, Deputy Director for Scientific Affairs, and Dr. Eng. Adam Lipka from the Department of Wireless Systems and Networks in Gdańsk. They presented papers dedicated to the security of satellite navigation systems and the RTGMS project.
Appreciation for the National Institute of Telecommunications
During the opening of the conference, Andrzej Żylis, Head Geodesist of Poland, thanked the National Institute of Telecommunications for its cooperation in activities related to the detection of GNSS signal interference. A commemorative gift was received by Prof. Mariusz Figurski.
In his opening remarks, the Head Geodesist emphasized the importance of the joint project carried out by GUGiK and the National Institute of Telecommunications, highlighting its role in strengthening the country’s resilience against threats related to disruptions of satellite navigation systems.
“PNT Shield” – technological and information security
In his presentation, Prof. Mariusz Figurski introduced the concept of the Polish PNT Shield — an integrated system for monitoring and protecting positioning, navigation, and timing (PNT) services, designed in response to the growing threats associated with GNSS signal interference.
The expert from the National Institute of Telecommunications pointed out that modern economies and critical infrastructure are highly dependent on satellite technologies.
GNSS is a critical service for various sectors of the economy, but at the same time it is infrastructure highly vulnerable to interference
- emphasized Prof. Figurski.
The speaker discussed the growing number of incidents involving so-called jamming and spoofing, meaning the intentional disruption or falsification of satellite signals. He stressed that the problem affects not only geodesy, but also aviation, energy, transport, telecommunications, and autonomous systems.
We must be aware of the technology
- he noted.
The Polish PNT Shield should be the answer to these threats.
Prof. Figurski also presented the assumptions behind the development of a multilayer monitoring system integrating data from various sources — ground-based, airborne, and satellite — while using artificial intelligence to detect and analyze interference. A particularly important component of this architecture is the RTGMS system being jointly developed with GUGiK.
RTGMS – a GNSS interference monitoring system
The presentation by Dr. Eng. Adam Lipka expanded on the earlier presentation by Szymon Wajda from GUGiK and on the film dedicated to the RTGMS project shown during the conference. The film illustrated the scale of the impact that GNSS interference can have on the daily functioning of society and the economy — from navigation and logistics problems to threats affecting geodetic measurements and the operation of critical infrastructure.
Dr. Lipka discussed in detail the architecture of the RTGMS system and the GNSS interference detection algorithms developed by the National Institute of Telecommunications. He explained that the system operates on three detection levels, with spectral analysis of radio signals playing a key role.
It is much easier to detect the fact of interference than to actually interfere with a GNSS receiver
- explained the IŁ expert.
The speaker also presented the results of field tests conducted in north-eastern and south-eastern Poland. As he emphasized, the measurements confirmed the effectiveness of the developed methodology and the high sensitivity of the system.
Satellite navigation interference is not an academic or theoretical issue. It is a phenomenon that genuinely affects the functioning of the state and the economy
- stressed Dr. Lipka.
The expert from the National Institute of Telecommunications also discussed plans for the further development of RTGMS, including the expansion of the monitoring network to cover the entire country, the implementation of new signal analysis algorithms, and the development of mobile versions of the system.
The conference in Ożarów Mazowiecki demonstrated that the security of GNSS systems is becoming one of the key challenges for public administration, critical infrastructure, and the modern economy. The participation of experts from the National Institute of Telecommunications confirmed the Institute’s important role in building national competencies in the field of monitoring and counteracting disruptions to satellite navigation systems.
