Object position data acquisition method, e.g. for GPS vehicle navigation, by verifying position data using attribute of receiver as verification criterion and comparing with threshold

摘要

Signals are transmitted from a positioning system to a receiver associated with the object, and position data are obtained from the acquired signals. The position data are subjected to a verification using at least one attribute (e.g. course, direction, distance or angle) of the receiver as a verification criterion, and comparing the value of the attribute with a threshold value. The position data are preferably filtered based on the result of the verification. An independent claim is included for a system for acquiring the position data of an object.
