In the system realized in this study, several air parameters are transmitted between model aircraft and ground station. System eqipment consists of a model aircraft, a transmitter and a receiver that has got min 4, max 8 channells capable of FM (Frequency Modulation) or PCM (Pulse Code Modulation); a personal computer (PC); an interfacing board capable of converting digital signal into analog signal and vice versa; an FM receiver; temperature sensing circuit; and an FM transmitter capable of sending the information on model aircraft on 74.1MHz frequency band with 0.2 seconds of interval. Flight and all sorts of movements of model aircraft is controlled from the ground station by radio waves. Temperature information of the air is transmitted to the receiver at ground station by FM transmitter placed on aircraft at 74.1 MHz frequency. Information sent from the aircraft to the ground station is processed by Delphi software.
