GNSS RECEIVER AND POSITIONING METHOD

摘要

PROBLEM TO BE SOLVED: To improve positioning precision by reducing the influence of multipath. SOLUTION: A GNSS receiver for performing positioning operations based on positioning signals transmitted from a GNSS satellite includes: a positioning operation section for performing positioning operations based on positioning signals from the GNSS satellite; a position estimation section for estimating the position of the GNSS receiver based on information other than positioning signals from the GNSS satellite; a route difference change rate estimation section for estimating the change rate of a route difference between direct and reflection waves; a weighting setting section for setting weighting between a positioning operation result and a position estimation result based on the change rate of the route difference; and a position operation section for obtaining the position of the GNSS receiver according to the set weighting.
