1. A Global Positioning System (GPS) receiver, comprising:
- 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.

8. A method for determining a position of a receiver using Global Positioning System (GPS) signals, comprising:
-
determining the position of at least a first GPS receiver using GPS signals; providing a correction factor to the position from a mapping software algorithm; seeding a navigation algorithm of the at least first GPS receiver with the correction factor; and calculating a new position of the at least first GPS receiver using the correction factor. - View Dependent Claims (9, 10, 11)

12. A navigation system for determining a position of an object, comprising:
-
a Global Positioning System (GPS) receiver; a processor, coupled to the GPS receiver; a database, coupled to the processor; and a display, coupled to the processor, wherein the display illustrates the position of the object on a map derived from the database, the position of the object being determined by at least a calculated position determined by the GPS receiver and a correction factor comprising a difference between the calculated position and a determined position based on the map derived from the database. - View Dependent Claims (13, 14, 15, 16, 17, 18)
