GNSS Interference Detection and mitigation
GNSS CYBERSECURITY
In our increasingly interconnected world, the accuracy and integrity of GNSS signals is paramount. GNSS receivers, numbering in the billions globally, are integral to myriad sectors, yet remain vulnerable to RF interference like jamming and spoofing. This poses threats to critical national infrastructure.
Cyntony supplier GPSPATRON specializes in high-precision GNSS interference detection, classification and protection solutions that support defense, law enforcement, and critical infrastructure.
The over all architecture is a distributed system for GNSS signal quality monitoring and protecting time-critical and coordinates-critical infrastructure against GNSS threats of low-latency spoofing, jamming and interference. The system consists of three-channel GNSS probes (GP-Probe TGE2) and/or one channel probes (GP-Probe DIN L1) plus a GP-Cloud software running on a private network or accessible over the internet to subscribers. Capabilities include:
- GNSS Interference Detection and Classification: comprehensive platform for real-time GNSS signal quality monitoring, logging, and post-analysis. The system supports various GNSS sensors and is capable of detecting, classifying, and localizing interference, including sophisticated coherent spoofing attacks.
- Advanced GNSS Sensors: GP-Probe TGE2 is designed for interference detection, classification, and localization. These sensors are equipped to handle complex spoofing and jamming scenarios, providing robust protection of timing for critical systems and infrastructure.
- Time Difference of Arrival (TDOA) Technology: GPSPATRON utilizes TDOA methods for GNSS interference geolocation, enabling precise identification of interference sources.
REAL-WORLD USE
GPSPATRON HQ is located in Warsaw, Poland, so they have a front-row seat to the nefarious actions of bad actors in the region. In partnership with the Gdnyia Maritime University, a five month study of GNSS interference in the Baltic Sea was conducted in the Baltic Sea. During this period, 84 hours of interruption were observed, the majority attributed to jamming rather than spoofing, consisting of multi-constellation jamming and multi-tone interference. Some interference events led to significant positioning errors, degrading accuracy from 3–5 meters to over 35 meters—posing a serious risk to navigation, port operations, and critical infrastructure. Interestingly, none of the GNSS disturbances during these five months were detected as ADS-B positioning anomalies. To read the detailed 55-page report, click BALTIC SEA GNSS INTERFERENCE.

Operates in tandem with GP-Cloud, this sophisticated instrument safeguards critical
infrastructure from GNSS disruptions using a high-performance three-channel GNSS probe with a built-in RF signal analyzer. It detects, classifies and localizes GNSS spoofing and jamming and can protect infrastructure from PPS time base degradation.
Provides GNSS interference detection and classification, PPS accuracy monitoring,
GNSS signal quality analysis, and logging. The device is easily installed between a GNSS antenna and a receiver or time server.
When an event is detected, the GNSS and PPS outputs are immediately disabled, preventing counterfeit signals from reaching your system.
Processes data from GP-Probes and monitoring of RTK base stations via RTCM@NTRIP and other GNSS receivers through NMEA@NTRIP, providing instant notifications of detected anomalies. Real-time interference analysis can distinguish sophisticated spoofing attacks on GNSS-dependent critical infrastructure. Users can conduct detailed post-analysis of recorded incidents.
