Latvia is demonstrating a proactive approach to maintaining the reliability of its high-precision satellite positioning services in the face of growing regional interference. The Latvian Positioning System (LatPos) is highlighting the importance of strategic monitoring, operational transparency, and proactive interference management.
Strategic Response to Rising Interference
Like other Baltic states, Latvia has seen a significant increase in GNSS interference in recent years. The Latvian Electronic Communications Office reported 820 cases of satellite signal interference in 2024, a dramatic rise from the 26 cases recorded in 2022. Affected areas are also expanding, according to the office.
Latvia’s response centers on the LatPos continuous operating reference station (CORS) network, a 27-site base-station system managed by the Land, Geology and Cartography Agency (LGIA). LatPos provides real-time RTK correction streams and archived data for post-processing. National reporting indicates thousands of annual connections and widespread professional use.
Technical documentation emphasizes signal-integrity and quality-control measures, including interference detection at the receiver level and routine quality checks using the receiver independent exchange format (RINEX). Planned improvements to Radio Technical Commission for Maritime Services (RTCM) and RINEX monitoring are detailed in Latvia’s national GNSS report.
Implications and Future Outlook
The LatPos model – government-supported maintenance and open access – is designed to lower barriers to adoption for a range of users, including small and medium-sized enterprises, surveyors, municipal engineering teams, and academic institutions. The system’s architecture relies on redundancy, public data archives, and published guidance to ensure data quality and continuity.
For practitioners, this translates to reliable corrections for surveying, accessible archived data, and established processes for addressing signal threats. Latvia’s approach could serve as a model for other countries facing similar challenges. It is likely that further enhancements to monitoring capabilities will be implemented as interference patterns evolve.
