Abstract

The invention relates to a positioning method for determining the position and orientation of a mobile unit having a receiver (3′), whereby the receiver (3′) is detected by a scanner (2′), said scanner (2′) determining at least the distance and a direction in relation to the receiver (3′). The radiation emitted by the sensor is detected by the receiver (3′) and the direction of incidence of radiation and the direction of incidence of radiation in relation to an axis of reception are derived while an offset of the incident radiation in relation to the axis of reception (EA) is determined. Position and orientation of the unit are derived from at least the distance, the direction in relation to the receiver (3′), the offset and the direction of incidence as the position information and the unit is optionally controlled via the optical connection (OV).
