GNSSnærstöðvar

GNSSnærstöðvar refers to a network of GNSS (Global Navigation Satellite System) reference stations. These stations are strategically placed ground-based receivers that continuously track signals from GNSS satellites like GPS, GLONASS, Galileo, and BeiDou. Their primary purpose is to provide highly accurate and reliable positioning data.

The data collected by GNSSnærstöðvar is crucial for various applications. It is used to establish and maintain national geodetic datums, which are fundamental reference frames for mapping and surveying. These stations also play a vital role in correcting atmospheric delays and other signal errors, thereby improving the accuracy of GNSS positioning for users in the vicinity.

In Iceland, GNSSnærstöðvar form part of the national infrastructure for precise positioning. This network supports a wide range of activities including scientific research, monitoring of tectonic plate movements, precise navigation for maritime and aviation sectors, and various engineering and land management projects. The continuous operation and data archiving from these stations contribute significantly to understanding and managing Iceland's dynamic environment. The data is often made available to researchers and professionals to foster further innovation and application development.
