Patent abstract

A method may be executed by a base station or mobile device to improve accuracy of a global positioning system (GPS)-based position or “geoposition” of the mobile device. A time-stamped first set of GPS data may be 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 base station and mobile device GPS data coincides. The GPS data includes code phase and pseudo-range data from each of the GPS satellites, and may include carrier phase data. A predetermined GPS position correction technique is used to generate a corrected geoposition of the mobile device using the GPS data. The corrected geoposition is then transmitted to the mobile device and/or an external response system such as a drone or first responder.
