PURPOSE:To make observation easy at all times by using a sky phone of the beam direction movable by the command operation from the ground thereby enabling the sky phone to be directed to the cold space of the cosmos at all times. CONSTITUTION:1 is a receiving antenna, and 2 is a sky phone of a movable beam which is made adjustable of the beam directing direction of the sky phone antenna within a 0 deg.-90 deg. range by rotating a reflection plate 9 by means of a motor 10. The reflection plate 9 is mounted to the motor 10 away from its center. 3 is a standard sound source, 4 is a comparing noise source, 5 is a receiver and 6, 7, 8 are switches. With this constitution, the directions of the sun and the satellite such as the moon are beforehand forecast through orbit calculation, and therefore, the sky phone is set in influence-free directions by moving its rotative driving part manually or by programmed commands from the ground. |
