PURPOSE:To adjust the direction of the antenna for an EPU remote monitoring controller easily and automatically by inputting data of position of a radio wave repeater point on a map, and by determining an antenna azimuth on the basis of the position data to automatically control the directional angle of the antenna. CONSTITUTION:When inputting a marker indicating a radio wave repeating point in a map data section 1, the map data section 1 calculates the latitude and longitude that indicate the position of a radio wave repeating point, and outputs calculated information to an antenna angle indicating section 2. The antenna angle indicating section 2, based on input latitudinal and longitudinal information, determines and stores an antenna azimuth, and outputs antenna rotating control data to an antenna control section 4 via a data transmission section 3. The antenna control & monitor section 4, based on input antenna rotating control data, carries out antenna angle control so that a FPU parabolic antenna 5 points at a radio wave repeating position. |
