Abstract:
1. An antenna control system for use in a communication system made up of combination of an antenna device and communication targets, the antenna device of which the positional information being known, comprising: first and second arms, which are arranged in parallel and in a non-opposing manner on the same plane, respectively having axes C a first antenna which is supported by the first arm so that the attitude can be directed arbitrarily with respect to the axis C a second antenna which is supported by the second arm so that the attitude can be directed arbitrarily with respect to the axis C a first rotating mechanism for rotating the first antenna about the axis C a second rotating mechanism for rotating the second antenna about the axis C an arm elevation adjustment mechanism for common adjustment of the first arm and second arm; and an arm azimuth adjustment mechanism for common adjustment of the first arm and second arm, the communication targets including two communication targets T 1 and T 2 of which the positional information or movement information is known, the antenna control system comprising: a first rotational angle detecting means for detecting the rotational angle of the first rotating mechanism; a first rotating mechanism control means for controlling the first rotating mechanism; a second rotational angle detecting means for detecting the rotational angle of the second rotating mechanism; a second rotating mechanism control means for controlling the second rotating mechanism; an elevation detecting means for detecting the elevation angle of the arm elevation adjustment mechanism; an arm elevation adjustment mechanism control means for controlling the arm elevation adjustment mechanism; an azimuth detecting means for detecting the azimuth angle of the arm azimuth adjustment mechanism; an arm azimuth adjustment mechanism control means for controlling the arm azimuth adjustment mechanism; a means D for calculating the plane P containing a triangle defined by the two communication targets T a means E a means E a means F a means F a means F a means F characterized in that, based on the calculation results from the means F 1 , F 2 , F 3 and F 4 , the elevation adjustment mechanism, the azimuth adjustment mechanism, the first rotating mechanism and the second rotating mechanism are controlled so that the first antenna and the second antenna can be pointed towards the communication targets T 1 and T 2 , respectively.
