GNSSverkostot

GNSSverkostot refers to the Finnish national network of Global Navigation Satellite System (GNSS) reference stations, managed by the Finnish Geodetic Institute (FGI). The network provides high-precision positioning data essential for various applications in geodesy, surveying, navigation, and other fields requiring accurate spatial information.

The GNSSverkostot consists of a dense array of continuously operating reference stations (CORS) distributed across Finland. Each station is equipped with dual-frequency GNSS receivers and antennas, enabling the collection of precise satellite signal data. These stations transmit their observations in real-time to users via the network’s data center, facilitating accurate positioning through differential GNSS techniques.

The primary purpose of GNSSverkostot is to support high-accuracy positioning services, including real-time kinematic (RTK) corrections, static surveys, and continuous monitoring of crustal movements. The network also contributes to scientific research, such as studies on Earth’s crustal deformation, sea-level changes, and climate-related observations.

GNSSverkostot is integrated with international GNSS networks, ensuring compatibility with global positioning systems and enabling seamless data exchange. The Finnish Geodetic Institute maintains and updates the network to enhance its reliability, coverage, and accuracy, making it a critical resource for both public and private sectors in Finland.

Access to the network’s data is typically provided through subscription-based services or open-access platforms, depending on the user’s needs. The infrastructure supports a wide range of applications, from infrastructure monitoring and agriculture to disaster management and urban planning.
