Patent ID: 8422032

Claim:
A position determination method for a unit which changes its position, the unit including a Global Navigation Satellite System receiver and an optically measurable reference point having a fixed spatial relationship relative to the Global Navigation Satellite System receiver and a geodetic device having a distance and direction measuring functionality, the method comprising: generating chronologically correlated position pairs by measuring: relative positions of the reference point in an internal reference system by optical measurement of in each case: distance; and at least one angle from the geodetic device to the measurable reference point; and Global Navigation Satellite System positions of the Global Navigation Satellite System receiver in an external reference system; coordinating relative and Global Navigation Satellite System positions which lie within a time window; deriving a fitted relationship between the external and the internal reference system from the position pairs; and determining the position of the unit of the geodetic device or of a measurable new point from the fitted relationship by a calculation unit of the unit which changes its opposition or of the geodetic device.
