The present disclosure suggests a method for determining at least one of a declination, an orientation and a position of an object, the method comprising the steps: pivoting a gyroscope, which gyroscope is mounted to the object, at a pivoting angular velocity about a swivel axis, measuring an undetermined pivoting of the object about an axis with the gyroscope, wherein the axis is different from the swivel axis; determining a component of the rotation of the Earth acting on the gyroscope using the undetermined pivoting, and the pivoting angular velocity; and either determining the declination of the object with respect to true north from the component of the rotation of the Earth acting on the gyroscope; or determining the orientation and the position of the object starting from an initial orientation and an initial position of the object using the undetermined pivoting, the pivoting angular velocity, and a distance travelled by the object, and compensating an influence of the determined component of the rotation of the Earth in the orientation and the position of the object; wherein the object is a vehicle or a part of a vehicle, which vehicle comprises a first vehicle part and a second vehicle part; wherein the first vehicle part is pivotable about the swivel axis relative to the second vehicle part; wherein the gyroscope is mechanically mounted to the first vehicle part; and wherein the method further comprises the step determining the pivoting angular velocity of the gyroscope about the swivel axis with a second sensor, which second sensor is distinct from the gyroscope.
