Abstract:
Using estimates of a receiver's altitude to determine where a receiver is located and to refine a positioning system's estimate of a receiver's position. Systems and methods determine whether a receiver is inside or outside a building, and may use the determination to confirm or adjust an initial estimate of the receiver's position. Various approaches for making the determination and for assessing the initial estimate of the receiver's position are described.

Claim (Index 1):
A method for improving an estimated position using altitude-based indoor/outdoor detection, the method comprising:\n determining an estimated position of a receiver; determining an estimated altitude of the receiver; identifying an altitude associated with the estimated position; determining if a relationship between the estimated altitude and the identified altitude meets a first condition; determining if the receiver is inside or outside a building depending on whether the relationship meets the first condition; and improving one or both of the estimated position or the estimated altitude based on determining whether the receiver is inside or outside.
