However, since the intelligent terminal senses the pitch angle of the satellite antenna to be adjusted through the gyroscope chip in the intelligent terminal, the operation requires that the direction of the plane main shaft of the data monitoring device is consistent with the direction of the actual main shaft of the paraboloid of the satellite antenna to be adjusted. Because intelligent terminal generally places on the connecting rod between antenna and the signal receiver, and there is the contained angle connecting rod direction and the antenna paraboloid actual main shaft direction, the antenna of different models the contained angle is different, causes compass and intelligent terminal to record data and has the error.
