database popyul rate and pressure used to unknown height of a unit with a high degree The system, apparatus and method are presented for determining. Each of the pressure from the one or more pressure sensors that are linked to the base station, the coordinates having a value of pressure read at any (x, y) (e.g., at sea level) are interpolated in order to determine the reference pressure. For example, a mobile station at an arbitrary coordinate (x, y) will record the pressure in the mobile station. The difference between the pressure and interpolated based on the pressure at the mobile station is determined, which may be interpreted as defined highly direct the mobile station. ;
