|Abstract: ||Abstract: In this paper, a barrier method for GPS positioning and multipath mitigation is
proposed. The present method can effectively eliminate the NLOS (non-line-ofsight)
delay errors and is also able to improve the location accuracy of a satellite
navigation receiver. A constrained WLS (weighted least-squares) estimator is derived
based on the proposed algorithm, which is able to properly estimate and
eliminate the multipath error contained in each satellite’s pseudorange. In our experimental
result, it is demonstrated that the proposed estimator can compute the
coordinate of a user location in an accurate fashion after estimating and removing
the measurement biases. This is done by suitably choosing the barrier functions.
The proposed method is well suitable in the positioning domain in contrast with
traditional GPS multipath mitigation methods which usually apply in the signalprocessing
domain. Furthermore, it can be used to identify the NLOS signal
where the LOS signal may not present in the received signal.
