文摘
- •
A new misalignment calibration method by rotating a parallelepiped frame is proposed.
- •
It does not need to know sensor attitude information or local dip angle.
- •
The calibration system attitude change angle is not strictly required.
- •
It can be widely used when sensors measure different physical information.
- •
Geomagnetic vector measurement error is reduced evidently.
