Abstract
A method of harmonizing a first inertial measurement unit and a second inertial measurement unit with each other includes the steps of: causing a control unit to compare the vectors measured by the inertial measurement units in order to determine a specific force difference and a rotation difference while taking account of the lever arms between the two measurement units; and causing the control unit to determine a harmonization value from the specific force difference and the rotation difference while taking account of the lever arms between the two measurement units. Navigation apparatus performs the method.
