Abstract
A base station almanac (BSA) stores directional forward link calibration (FLC) values that correct for differences between the listed locations of base station antennas and the actual locations of the antennas. Each directional FLC value is specific to wireless signals that are transmitted from a particular base station antenna and propagate toward a particular receiving area. A mobile station operating in a receiving area measures a wireless signal from a base station antenna located outside of the receiving area to obtain a signal measurement. The location of the mobile station is determined by applying a positioning algorithm that uses the signal measurement corrected by the directional FLC value for that particular combination of base station antenna and receiving area.
