に普及しつつある。An embodiment of the present invention will be described in detail with reference to the drawings. Since a helicopter is often used as a mobile relay station when a television station broadcasts a program from the outdoors, especially when relaying while moving, this case will be described as an example. In order for the mobile relay station and the base station to communicate with each other, the directions of the antennas of both of them must be properly facing each other. Since the position of the base station is fixed, it suffices to measure it once and obtain its latitude and longitude and altitude information. However, since the mobile relay station is constantly moving, it is necessary to know the position in real time. G used as the position measuring method
PS (Global Positioning Sys)
A positioning system using satellites receives signals emitted by a plurality of GPS satellites whose geographical positions are precisely known, and the phase difference between the signals arriving from each satellite causes the geographical position of the receiver, that is, The latitude, longitude, and altitude are calculated, and the measurement accuracy is extremely high, about 1 / 1,000,000. This measuring device is gradually becoming popular in ships and aircraft.
