PURPOSE:To control the device exactly with a simple configuration by making the reception level characteristic of the antenna a quadratic curve and by controlling the azimuth and elevation angle of the antenna according to the difference between the maximum value of said quadratic curve and the maximum value of the reception level that is being received at present. CONSTITUTION:A reception level signal that is received by the beacon receiver 2 through the antenna 1 is provided to the step tracking device 5. The step tracking device 5 includes the A/D converter 51 and the arithmetic processor 52. Both data of the azimuth and elevatuon angle of the antenna, which are detected by the angle detector 6, are fed to the arithmetic processor 52. A driving signal is given to the driving gear 4 by the arithmetic processor 52, and the driving gear drives and controls the azimuth and elevation angle of the antenna. |
