Abstract:
Chronologically correlated position pairs are generated in a position determination method using a unit, particularly a working machine (4), that changes its own position, having a GNSS receiver (2) and an optically measurable reference point (A) disposed in a spatially stationary manner, particularly an all-around prism (3), and having a geodetic device with a distance- and angle-measuring functionality, particularly a tacheometer (1). To this end, relative positions of the reference point (A) are determined in an interior reference system by optically measuring distance and at least one angle of the geodetic device to the reference point (A) and GNSS positions of the GNSS receiver in an exterior reference system. Equal times, or relative and GNSS positions allocated to a time frame are associated with each other, particularly in pairs, thus forming position pairs. In addition, the position pairs perform a derivation from a balanced relationship between the exterior and interior reference system, particularly from balanced transformation parameters, and determine the position of the unit, of the geodetic device, and/or of the measurable new point from said balanced relationship.
