1. A mobile reference station for production of correction signals for a differential position-finding device, comprising:

  • a position-finding signal receiver for reception of signals from satellites in a position-finding system;

    an electronic processor, which is connected by a transmission unit to a radio antenna and is designed to receive position signals from the position-finding signal receiver and to derive correction data from these position signals, which correction data can be modulated by the transmission unit onto radio frequencies and can be transmitted via the radio antenna; and

    the processor further connected to an inertial sensor that can be operated to use signals from the inertial sensor to calculate a variable which is dependent on any position change of the reference station and to produce an error signal when this exceeds a predetermined threshold value.
