Abstract
Estimating an unknown position of a receiver. In some embodiment, trilateration techniques that quantify uncertainty in the estimate of the unknown position are applied. One such technique for estimating a two-dimensional or three-dimensional position of a receiver uses an L-1 norm computation instead of an L-2 norm computation.
Claims20
A method for estimating one or more positions of a receiver using signals received from a network of transmitters, the method comprising:
- estimating a first latitude and a first longitude of first position of a receiver using a first objective function that calculates an L-1 norm of residuals.
