METHOD AND APPARATUS FOR TRACKING A GLOBAL NAVIGATION SATELLITE SYSTEM WITHIN THE CONSTRAINTS OF AN INDOOR FACILITY

摘要

A method and chipset for tracking a global navigation satellite system (GNSS) within the constraints of an indoor facility. The method includes receiving assistance information on the GNSS on a mobile communication system; and sorting orbiting satellites within the GNSS by elevation angles. Additionally, lower elevation satellites are correlated within the GNSS prior to correlating higher elevation satellites.
