Device and Method for Improving Geographic Position Accuracy of a Global Positioning System-Based Mobile Device

摘要

A device and method which improves the accuracy of a global positioning system (GPS)-equipped mobile device. A time-stamped first set of GPS data is received via a GPS receiver, e.g., of the base station. A second set of GPS data describing a geoposition of the mobile device is received from the mobile device by the base station. A time of collection of the GPS data coincides. The GPS data includes code, carrier-phase, and pseudo-range information from each of the GPS satellites. A predetermined GPS position correction technique is used to generate a first corrected geoposition of the mobile device using the GPS data. Corrected, carrier-smoothed geoposition is generated as a second corrected geoposition using a carrier smoothing operation. The second corrected geoposition is transmitted to the mobile device and/or an external response system such as a drone or first responder.
