AUTOMATIC ATTITUDE CONTROL SYSTEM FOR LASER COMMUNICATION DEVICE AND AUTOMATIC ATTITUDE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an automatic attitude control system for a laser communication device capable of controlling the attitude so that the laser communication devices face each other and making communication possible, and an automatic attitude control method.;SOLUTION: The position information of the laser communication device is computed on the basis of GPS data transmitted from the laser communication device 1, the correction regions 29 of the laser communication devices 1 on the communicating party side respectively are computed on the basis of the position information of the two laser communication devices 1, and a plurality of measurement points 31 and 32 are set in the respective correction regions 29. The control angle of the laser communication device 1 is computed so that the optical axis of a laser 3 is turned to the measurement points 31 and 32, the gain value of the laser 3 at the control angle is acquired, and the gain value is stored together with the angle. The attitude is controlled to an azimuth angle and an elevation angle for the time when the gain value is the highest among the stored gain values.;COPYRIGHT: (C)2008,JPO&INPIT
