Dear Colleagues,
I am pleased to share the findings of a recent six-month study conducted by GPSPATRON in collaboration with Gdynia Maritime University, focusing on in the Baltic Sea region.

Key Findings:
- A total of 84 hours of GNSS interference was recorded, with October experiencing the highest activity, including six major jamming events totaling 29 hours.
- The study identified two primary interference types: multi-constellation jamming, prevalent during the summer months, and multi-tone interference, which emerged in October.
- Some interference events lasted more than seven hours, significantly affecting GNSS-dependent maritime navigation and port activities.
- Despite extensive ground-level interference, ADS-B-based monitoring systems failed to register corresponding events, highlighting their limitations in assessing terrestrial threats.
These findings underscore the critical need for dedicated ground-based GNSS interference monitoring networks to protect maritime operations and other critical infrastructures.
For a comprehensive understanding of the study and its implications, I encourage you to download the full report, which includes detailed statistical analyses, spectrograms, and expert insights into the detected interference patterns. Access the report here:
