Gps - based method for improving the relative position determination with the use of neighbour entity information

摘要

A method and a system for determining a relative position between a carrier vehicle, and a remote vehicle using a technique is provided with a indirectly assisting entity. A gps - position of the carrier vehicle and of a remote vehicle is preserved. The number of common satellites, the gps - data for the carrier vehicle and the remote vehicle providing, determined. It is an indirectly helping entity are identified which a common number of satellites in communication between the carrier vehicle and / or the remote vehicle has, the greater than the number of common satellite between the carrier vehicle and the remote vehicle is. It is a relative position between the carrier vehicle and of the indirectly assisting entity, and between the remote vehicle and the determined indirectly assisting entity. It is a position of the carrier vehicle relative to the remote vehicle as a function of the determined position of the carrier vehicle and of the remote vehicle relative to said determined indirectly assisting entity.
