Latvia’s national positioning system is demonstrating the importance of strategic monitoring and transparent operations in maintaining high-precision GNSS services as regional signal threats increase. The Latvian Positioning System (LatPos) network continues to provide critical positioning data across the country, even as interference incidents rise.
Strategic Moment
Like other Baltic states, Latvia has seen a significant increase in GNSS interference in recent years, with both the frequency and severity of incidents growing. The Latvian Electronic Communications Office reported 820 cases of satellite signal interference in 2024, compared to just 26 cases in 2022, and noted that affected areas are expanding.
Latvia’s national GNSS report details planned improvements to Radio Technical Commission for Maritime Services (RTCM) and receiver independent exchange format (RINEX) monitoring. These measures are designed to quickly identify jamming and spoofing incidents and device-level anomalies, reducing downtime and informing mitigation strategies.
LatPos is a 27-site base-station system providing real-time RTK correction streams and archived data for post-processing, according to the Land, Geology and Cartography Agency (LGIA). The system’s funding and governance model, which includes government support and open access, lowers barriers to adoption for various users, including SMEs, surveyors, municipal engineering teams, and academia.
The system’s architecture relies on multi-station redundancy, public RINEX archives, and published operational guidance to ensure data quality and continuity. This provides reliable RTK corrections for survey campaigns, accessible archived data for high-precision post-processing, and institutional processes to respond to signal-quality threats.
LatPos demonstrates practical strategies for detecting, monitoring, and mitigating jamming and spoofing, offering lessons for CORS networks worldwide facing similar interference threats. National reporting through 2025 documents thousands of annual connections and heavy professional uptake of the system.
