What measurement method does the satellite compass rely on to determine attitude?

Passive attitude control is a method that uses the dynamic characteristics of the satellite itself and environmental moments to achieve attitude stability. There are also some batteries on the satellite, which measure the attitude of the satellite through the attitude sensor on the satellite. The attitude control method of modern artificial satellites is as follows. The attitude information of the ship such as the ship's turning angular speed must be pointed out by a Feng Shui master.

The Feng Shui compass overlaps with the red line in Tianchi when measuring the direction of a fixed object. The satellite attitude control method is also different, because there is no longitude and latitude reticle, and the passive attitude control method has spin stability.

See the picture for example:

You must put the iron on your body first. Satellite attitude control can be divided into passive attitude control and active attitude control. Place the compass between the chest and abdomen, close to or parallel to the edge of the object being measured
