[0010] like figure 1 Shown to measure the angle between the x-axis and the z-axis As an example, the measurement process is divided into three steps:
[0011] 1) Measure the angle between the geomagnetic field E and the x-axis;
[0012] 2) Measure the angle between the z-axis and the plane XOE;
[0013] 3) Calculate the angle between the x-axis and the z-axis .
[0014] The specific measurement steps are as follows:
[0015] 1. Measure the angle between the geomagnetic field E and the x-axis: first record the magnitude of the geomagnetic field with an optical pump or a proton magnetometer, and record it as ;
[0016] Apply a magnetic field of the same strength as the earth's magnetic field in the direction of the x-axis ,like figure 1 As shown, OE is the direction of the geomagnetic field vector, and the other two axes do not apply a magnetic field. At this time, the output of the optical pump is recorded as , the angle between the X-axis and the geomagnetic ...
