Abstract: The present invention relates to a system for locally precise application of substances to useful areas of farmland and woodland and a corresponding method. The system comprises at least one multiple rotary wing aircraft, which contains at least one electronic control device for controlling the flight movements, which steers the multiple rotary-wing aircraft autonomously on predefined flight paths. The electronic control device contains at least one processing unit, at least one receiver for signals of a global satellite navigation system for position determining and an inertial measurement unit for detecting movement data of the multiple rotary-wing aircraft.

Abstract: A description is given of a receiving device for receiving data. The receiving device extracts from the received data a specific part thereof and, depending on the content of the extracted data, decides how it must handle the received data. The receiving device described is distinguished by the fact that it determines, depending on a part of the extracted data, how the received data might have to be handled, and that, taking account of the result of this determination, it determines how the received data are actually to be handled. Such a receiving device can decide, quickly and simply with a low outlay under all circumstances, how the received data are to be handled.
