Abstract
In a wireless mobile communication system having a position determination service, base station information is stored in a base station almanac. In addition to the position of the base station antenna, forward link delay calibration, and base station identification information, a base station almanac record includes the center location of the base station sector coverage area, the maximum range of the base station antenna, the terrain average height over the sector coverage area, the terrain height standard deviation over the sector coverage area, round-trip delay (RTD) calibration information, repeater information, pseudo-random noise (PN) increments, uncertainty in the base station antenna position, uncertainty in the forward-link delay calibration, and uncertainty in the round-trip delay calibration.
