ABSTRACT:
A system and method examines the quality of a positioning signal acquisition assistance window of an assisted position location system. The fit of acquisition assistance windows is examined using a posteriori knowledge of specific, or hypothetical, position measurements from a mobile station. A base station almanac manager compares mobile station measurement data to acquisition assistance window data, records an outcome based upon the comparison including a window quality value (WQ), or range of window quality values. Source data used in the generation of acquisition assistance windows is adjusted according to the window quality value.
