Conventionally, an information exchange method used between an aircraft and a control tower includes a transceiver provided in a cockpit of an aircraft serving as a mobile unit and a transceiver provided in an air traffic control room serving as a base station. When the pilot and the controller want to transmit voices to and from the aircraft, they press the buttons on the handsets of the transceivers (press), and exchange information through press talk, which is a method of emitting voice (talk). It is a press talk call system.

[0004] In the conventional position reporting system for notifying the control tower of the position of the aircraft, the pilot transmits and receives the current position (latitude, longitude, and altitude) of the aircraft obtained from the position measuring device by the aforementioned press talk communication system. It was to be communicated to the controller using a machine.

[0005] As shown in Fig. 4, the configuration of a conventional position reporting system is as follows: a mobile transceiver 10 installed in a mobile (aircraft) and a base station transceiver installed in a base station (air traffic control room). Machine 20.
