Second, description of the productThe product has built-in three-axis magnetoresistive sensor and two-axis tilt sensor. The output direction is the angle between the projection of the north axis of the compass in the horizontal plane and the projection of the Northern Line of the geomagnetism on the earth. Because of the tilt and pitch angle compensation, the projection of the compass pointing changes little in the tilt or pitch conditions. Thus the influence in those conditions is small.The compass is designed mainly for the antenna for satellite communications. And the inclination output of the compass has the features of small temperature drifting, good repeatability, and low orthogonal interference. In practical application, the angle precision can meet the requirement of measurement accuracy of C-band or KU-band antenna (the antenna with a diameter shorter than 2m) of the satellite communications.The compass is a sensor for detecting the magnetic field, and it can not differentiate the interference magnetic field and the Earth’s magnetic field timely and accurately. Thus, to ensure the accuracy, it is necessary to provide a location of small magnetic field interference. Meanwhile, to reduce the linear acceleration and the rotational acceleration of the compass is another key to ensure the accuracy.
