Abstract: The present invention determines optimal positions of a variable antenna using an artificial intelligence-based genetic algorithm (GA). The GA acquires a fitness value for an individual of a genetic algorithm population by updating positions of the antenna. The population improves through an evolutionary computational process using a fitness measure based on the signal strength. At the end of the process, the system positions the antenna to the best position found by the GA. Therefore, the final position gives exceptionally clear reception for a chosen received frequency.

Abstract: A direction adjustment indicator for a satellite radio wave receiving antenna comprises a demodulating circuit to demodulate a satellite radio wave received by the antenna, a peak holding circuit always to output a held peak value of the demodulated output of the demodulating circuit, a comparator circuit and a display element. The comparator circuit compares the instantaneous value of the demodulated output and the held peak value, and outputs a signal when both values are equal and another different signal when both values are not equal. The display element gives two different kinds of display in accordance with the signals. While the azimuth angle of the antenna is varied in one direction, a peak value of the demodulated output is held and while the angle is varied in the opposite direction, the optimum azimuth angle is displayed for which the instantaneous value of the demodulated output agrees with the held peak value.

Abstract: A device for rotating a parabolic antenna (10) by an actuator (20) to enable reception of electric waves transmitted from a plurality of satellites with the antenna (10). A data for rotating the antenna (10) to enable reception from each satellite at a predetermined receiving position is stored in a ROM (24). A CPU 22 sets the antenna (10) in a position corresponding to the data in the ROM (24) for each satellite different initial receiving from the former for each satellite. From this state, the antenna (10) is moved east and west to detect disappearance of a synchronizing signal which is part of a signal from a tuner (18) by a synchronizing signal detector (50), and the midpoint of the positions of disappearance of the synchronizing signal in the east and west is stored in a RAM (26) as a position of the best receiving condition. The data in the RAM (26) is read out by a control unit (36) and the position of the antenna (10) is changed correspondingly.

Abstract: In an antenna system for tracking a satellite, a prediction of the angular orientation of the satellite relative to the antenna as a function of time is obtained from the orbital parameters of the satellite. The mechanisms for controlling the angular position of the entire antenna structure then "drive" the entire structure so as to point the antenna beam towards the predicted position of the satellite as the satellite progresses in its orbit. The "drive" instructions are perturbed slightly so as to cause the antenna beam to "dither" slowly about the predicted satellite positions. The variations in signal strength produced by the dither are then used to determine the azimuth and elevation errors. The orbital parameters upon which the predictions are based are then adjusted so as to minimize the observed azimuthal and elevation errors. Because any error in the orbital parameters changes only very slowly, a relatively slow "dither" and a long time constant can be used in the correction process.

The second antenna is now placed in its location of maximum received signal level and transmits while the first antenna is displaced in one of the patterns and its level of receipt of transmitted energy is monitored. The first antenna is now placed in its location of maximum received signal level.
