The patent or application file contains at least one drawing executed in color. The rotary element is rotatably disposed on a lower portion of the case. The amplitude of this fluctuation is divided by an average current value and output as an amplitude index. Observations of GNSS signals are obtained from each of a plurality of GNSS satellites. In this way, the same type of semiconductor circuit chips for which the boundary controller is provided can be stacked, thereby manufacturing the semiconductor apparatus. And, selecting the location of the dumping point according to the results of the comparison.
