っても回転数の変化か生じるといり欠点があった。Also, even if the rotation starts in synchronization with the time, it is difficult to keep the number of rotations per unit time constant over a long period of time! However, it also has the disadvantage that the rotational speed may change due to changes in ambient temperature, wind generation, changes in load, etc.

It is an object of the present invention to provide an antenna rotation control device which maintains the number of rotations per unit time of the antenna constant over a long period of time while inputting a time signal and comparing the ideal angular position of the antenna with the ideal angular position of the antenna.

Switch from the output of variable resistor (4) to the output of variable voltage generator +81.This variable voltage generator;8)
As mentioned above, since the pressure sensitive signal that determines the speed is selectively outputted, the antenna (1) follows this and rotates at the appropriate speed. This prepared voltage is generated corresponding to the difference between the actual angle and the ideal angle of the air $ tl) as described above, and the air #! 11) or the next Nth rotation is selected so that the ideal time will be reached. By repeating this operation, the antenna (1) rotates in units of N rotations that are used to collect l data, and as a result, accurate data can be collected with each rotation. .
