Vehicle positioning technology

Abstract

The present invention provides an apparatus, system, and method for improving the accuracy of vehicle positioning (also known as location determination). [Solution] Various vehicle technologies to improve positioning accuracy despite various factors affecting signals from navigation satellites. For use in differential algorithms, such positioning accuracy is improved by determining an offset and communicating the offset in various ways, or by sharing raw positioning data among multiple devices where at least one knows its position well enough.
