Electronic compass has its own unique advantages: the electronic compass itself is small in size, light in weight, the acquisition and solution of azimuth information is real-time, and the output digital signal can make it more direct and convenient in the subsequent use. At present, the development of digital compass sensor technology has been relatively mature, so that it has certain advantages in measurement accuracy and manufacturing cost. Because digital compass is widely used in practice, a large number of high-precision, low-cost electronic compass products suitable for large-scale industrialization need to be put into production.
In today's society, the design and research of navigation and orientation instruments have important value and significance. With the expansion of human exploration in the space field, the stability maintenance, tracking guidance and other functions of artificial satellites, space shuttles, missile weapon systems and various platforms all need the support of navigation orientation technology and corresponding attitude adjustment devices. To sum up, obtaining orientation information and realizing the corresponding attitude control play a fundamental role in various scientific research and engineering realization.
According to the characteristic that the geomagnetic field changes little in a certain time range, it can be considered that the geomagnetic information at the same place is fixed in a short time, and the azimuth information such as heading Angle and attitude Angle can be calculated by the electronic compass according to the geomagnetic intensity information measured.
1.The principle characteristics of the geomagnetic field
As the basic physical quantity of the earth, the geomagnetic field has a direct effect on the physical characteristics of electric and magnetic substances in the earth environment. The characteristics of the Earth magnetic vector field provide a basic coordinate system for azimuth information, and the use of geomagnetic information navigation is stable and reliable, without receiving external information, with good concealment. The geomagnetic field is generated from the structure of the earth itself. There are many magnetic elements and substances in the earth's interior, which produce free flowing electrons under the influence of the extreme environment inside the Earth. These free electrons lead to the improvement of the conductivity between the earth's inner core and outer core, resulting in the flow and movement of free electrons between different strata. This makes the earth as a whole have a stable magnetic field on a macro level, which is equivalent to a magnetic dipole with a constant magnetic field existing in the center of the Earth, resulting in the production of north and south magnetic poles. Figure 1 shows the schematic diagram of the distribution of the Earth's magnetic field.
