Abstract

A near field navigation system is equipped with a base segment provided on a base structure. The base segment includes at least four transmitters. Each transmitter is provided with a base antenna and the base antennas are positioned relative to each other at known distances. A user segment is provided on a user structure, the user segment including at least one receiver, at least one user antenna connected to the receiver, and a processing unit connected to the receiver. The receiver and each of the transmitters together form distance measuring units and the processing unit is adapted to calculate the relative three-dimensional position data of the user structure with respect to the base structure on the basis of distance data obtained from the distance measuring units.
