Abstract
A reference station produces correction signals for a differential position-finding device. The station utilizes a position-finding signal receiver for reception of signals from satellites in a position-finding system and an electronic processor, which is connected by a transmission unit to a radio antenna. The electronic processor is designed to receive position signals from the position-finding signal receiver and to derive correction data from these position signals. The correction data can be modulated by the transmission unit onto a radio frequency signal and can be transmitted via the radio antenna. The processor is connected to an inertial sensor to calculate any position change of the reference station, and to produce an error signal when the calculated magnitude of the position change exceeds a predetermined threshold value.
