Bredområdekorreksjoner, sometimes translated as wide-area corrections, are a technique used in precision positioning to improve the accuracy of Global Navigation Satellite System (GNSS) receivers. These systems rely on signals from satellites to determine a location, but atmospheric conditions and satellite orbit errors can introduce inaccuracies.

Wide-area correction systems work by establishing a network of precisely surveyed ground stations spread across a large geographical region. These stations continuously monitor GNSS satellite signals and calculate the errors that affect positioning. This error information is then processed and broadcast to users within the coverage area, typically via satellite or a cellular network.

GNSS receivers equipped to receive these corrections can then apply them in real-time to their own calculated positions. By compensating for the measured errors, the receiver can achieve significantly higher accuracy than it would be able to on its own. This enhanced precision is crucial for applications such as surveying, precision agriculture, autonomous vehicle navigation, and infrastructure monitoring. The broader the area covered by the correction network, the more widespread the benefits of this technology become.
