发明名称 GPS POSITION ACCURACY USING FEEDBACK FROM A MAP DATABASE
摘要 A mapping software feedback correction system for use with GPS receivers and GPS enabled devices. A Global Positioning System (GPS) receiver in accordance with the present invention comprises a Radio Frequency (RF) section, the RF section adaptable to receive at least one GPS signal from at least one GPS satellite; and a baseband section, coupled to the RF section, wherein the baseband section performs calculations to determine a geoposition of the GPS receiver based on the at least one GPS signal, wherein the geoposition is determined based on a mapping software correction factor.
