Claims20
1-19. (canceled)
A method comprising:
- receiving signals associated with multiple antenna elements;
- determining constraint information based upon an atmospheric pressure measurement taken at an apparatus;
- and
- using the received signals and the constraint information to determine the position of the apparatus, wherein the constraint information is dependent upon a ratio of a reference pressure and the taken pressure measurement.
