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.

A method of monitoring equipment of an agricultural machine includes taking a process computer and connecting the same to at least one sensor measuring an operational characteristic of the agricultural machine. The process computer evaluates the data received from the sensor and checks whether they indicate a fault of the agricultural machine. In this case, the data may be below and/or above a predetermined threshold. When such as fault or error occurs, the process computer submits a fault message to a remote station using a communications interface. The fault message contains a fault information identifying a type of the fault.

A device for the measurement of the moisture of harvested crop including a measurement capacitor ( ) with two spaced electrodes ( ), between which harvested crop can be introduced. The capacitor ( ) is connected to an inductance ( ) of a resonance circuit ( ). For improved precision, it is proposed that the resonance circuit ( ) be supplied with a measurement signal in the form of an alternating voltage with variable frequency and that a parameter of the resonance circuit ( ), preferably resonant frequency dependent upon the capacitance of the capacitor ( ), be detected at various frequencies and used for the determination of the moisture.
