Abstract
The method of aligning an inertial unit having an axially symmetrical vibrating sensor that generates vibration comprises the step of establishing the vibration in a position for which the sensor presents variation in drift error that is the smallest relative to variation in drift error for other positions of the vibration.

A method of aligning an inertial unit having an axially symmetrical vibrating sensor that generates a vibration, wherein the method includes the step of establishing the vibration in a position for which the sensor presents drift error variation that is minimized relative to the drift error variations for other positions of the vibration.
An inertial unit comprising an axially symmetrical vibrating sensor, and means for exciting the sensor to generate vibration, wherein the inertial unit further comprises means for establishing vibration in a position for which the sensor presents variation in drift error that is the smallest compared with variation in drift error for other positions of the vibration.
