ABSTRACT:
A precise 3D position-finding system and method comprises at least the following elements: a set of beacons working on the basis of differential global positioning satellites (DGPS), the beacons being connected to one another and temporally synchronized, spread-spectrum radio means between the members of the network whose position is to be located and said beacons, and a computation station. The computation station is provided with a processor adapted to finding the position of one or more elements from a list of direct paths and/or multiple paths with the time and direction of arrival of each of the direct paths and/or multiple paths, and from the position of the beacons and in taking account of data that represents obstacles.
