How does a D-GNSS reference station work?
D-GNSS gives us the opportunity to improve GNSS positions from 5 - 10 m accuracy to < 2 cm. This requires correction data from a reference station. But how does a reference station work?The reference station continuously measures your location using a GNSS receiver. However, it knows your actual location and can therefore calculate the error in the current GNSS position. It is particularly important that a reference station is calibrated as accurately as possible, i.e. that the actual position is known. Traditional measuring methods that are not based solely on GPS, such as a total station or a total station, are suitable for calibrating.
