Relationship between sensor non-orthogonal coordinates and the spacecraft reference frame, as well as the definitions of the misalignment angles, α and β. a Angles of measurement directions in an orthogonal reference frame represented by ΦX, ΦY, ΦZ, ΘX, ΘY, and ΘZ are determined in the ground calibration. b O1 is defined as an orthogonal coordinate that has the same X-direction and coplanar XY with the sensor. c Sensor misalignment is expressed by inclination angles α and β of O1 in the reference coordinate system with respect to the spacecraft spin axis
