Abstract
A declination of an object, an orientation of the object and/or a position of the object can be determined using a gyroscope. In this regard, the gyroscope can be mounted to the object. The gyroscope can be pivoted. An undetermined pivoting of the object about an axis with the gyroscope can be measured. A component of a rotation of Earth acting on the gyroscope can be determined using the undetermined pivoting and the pivoting angular velocity (wcarousel). At least one parameter set can be determined. The pivoting angular velocity (wcarousel) of the gyroscope about the swivel axis with a second sensor can be determined.
