The Principle Of The Action Of Electronic Magnetic Compass In The Horizontal Platform Attitude Measuring Unit.

The horizontal platform attitude measuring unit is a key component of the three-axis moving medium-passing antenna, and is characterized in that the angle between the sensor mounting plane and the antenna electric axis is determined by the preset horizontal platform attitude measuring unit, so that the antenna is horizontally aligned with the star. The sensor mounting plane of the platform attitude measuring unit is parallel to the ground level. The two-dimensional electronic magnetic compass is a key component in the horizontal platform attitude measurement unit. Its function is to store the azimuth parameters during the process of capturing the satellite, and to guide the antenna orientation to the theoretical azimuth of the satellite. The advantages of projection magnetic compass compared to other magnetic compasses

     The electronic magnetic compass determines the azimuth by the sensitive earth's magnetic field vector. In the presence of more ferromagnetic materials, the distribution of the earth's magnetic field vector will change, and the size and direction will also change. These changes cause a large deviation in the azimuth of the output of the electronic magnetic compass, which in turn affects the accurate alignment of the antenna to the satellite.
