摘要
A multi-band remote control system for an unmanned aircraft is provided to use more channels by using a PCM(Pulse Code Modulation)-type encoder, and to use multiple frequencies, thus precise control of the unmanned aircraft is possible. A transmitter(110) comprises the followings. A controller(111) generates a control signal by receiving a desired action, and outputs a VHF(Very High Frequency) control signal or a servo control signal. A VHF transmission device(114) receives the VHF control signal to output a VHF signal. An encoder(112) receives the servo control signal to output an UHF(Ultra High Frequency) control signal. An ultra high transmission device(113) receives the UHF control signal to output an UHF signal. A receiver(120) comprises the followings. A VHF receiving device(124) receives the VHF signal. An UHF receiving device(123) receives the UHF signal. A decoder(122) outputs the UHF signal as a servo control signal. A selector(121) selects the servo control signal or the VHF signal received from the decoder(122) and the VHF transmission device(114). An operation of an unmanned aircraft(130) is controlled by the selected servo control signal or VHF signal.
