ABSTRACT:
Systems and methods that mitigate errors in positioning systems, by employing signal strength(s) of signal sources (e.g., towers adjacent to a mobile unit.) Such mitigation system verifies whether the mobile unit receiving GPS data is in static position (e.g., not moving) or is moving (e.g., dynamic position), and evaluates accuracy of the GPS reporting (e.g., discarding GPS data in static position and trusting GPS data in dynamic position).
