Abstract: A transmitting apparatus and receiving apparatus for indicating a position can be remotely controlled. The transmitting apparatus includes a means for measuring an inclined angle of a transmitter with respect to a gravity axis of the earth to measure and transmit the inclined value of the transmitter in addition to transmitting waveforms having different phase angles and the same frequency simultaneously and the receiving apparatus is configured by a receiving apparatus that receives and ultimately amplifies the transmitted signal and processes the amplified signal so as to acquire positional information regarding a shift of a phase which is shifted from a reference signal.

Abstract: Disclosed is a remote position designation system for designating an optional position on a plane at a place remote from the plane. The remote position designation system includes a transmitter unit including transmitters adapted to transmit, as a position signal, signals of the same frequency, but having different phases, in a simultaneous fashion, respectively, a receiver unit for receiving the signals transmitted from the transmitters of the transmitter unit in the form of a composite signal, amplifying the received composite signal to a saturation level, and conducting a signal processing for the amplified signal to obtain position information associated with a phase shift of the amplified signal from a reference phase, and a control unit for generating a control signal adapted to display a position designated by the position signal from the transmitter unit on a screen, based on the position information from the receiver unit.
