ULTRA-WIDEBAND ASSISTED PRECISE POSITIONING SYSTEM AND METHOD

An ultra-wideband (UWB)-assisted precise positioning system, which includes a plurality of mobile base stations (MBSs) and a central control base station (CBS). The central CBS and the MBSs are configured to: measure, by the UWB communication module, distances between the MBSs, such that the moving...

Zusammenfassung:	An ultra-wideband (UWB)-assisted precise positioning system, which includes a plurality of mobile base stations (MBSs) and a central control base station (CBS). The central CBS and the MBSs are configured to: measure, by the UWB communication module, distances between the MBSs, such that the moving module controls the MBSs to have a predetermined distance from one another and form a predetermined pattern; configure the global satellite positioning (GPS) modules to perform positioning to obtain a plurality of initial positions; execute a pattern search algorithm to generate a plurality of corrected positions; generate a plurality of predicted positions to be input to a cost function for finding a plurality of final predicted positions having relatively smallest errors; measure, by the UWB communication module, distances of a test object relative to the MBSs and calculate a position of the test object.
