Abstract
A method and apparatus for qualifying a Satellite Positioning System (SPS) location determination. A method in accordance with the present invention comprises determining a constellation of satellites used in the location determination, making a measurement set based on signals received from the constellation of satellites, comparing the measurement set and the constellation of satellites used in the location determination to a predetermined threshold, and reporting the location determination only when the threshold is not exceeded. Such a method further optionally includes the threshold being user-selectable, the threshold being adjusted or disabled based on a pre-defined scheme, the threshold being adjusted in a sequential form based on a pre-defined scheme, and the measurement set being made in a Global Positioning System (GPS) receiver.
