Abstract

A navigation signal receiving apparatus for determining a position based on a navigation signal sent from an artificial satellite, the apparatus includes (a) a positioning unit sampling range data from the navigation signal at a first time interval, (b) an averaging unit averaging the range data at a second time interval of a lower rate than the first time interval, and (c) a positioning process unit calculating a position based on the range data averaged by the averaging unit.

Description

technical field [0001] The invention relates to a navigation signal receiving device and a navigation signal receiving method, in particular to a navigation signal receiving device and a navigation signal receiving method with reduced multipath errors. The present invention can be widely applied to navigation signal receiving devices such as GPS (Global Positioning System) receivers, GALILEO receivers or GLONASS (Global Navigation Satellite System) receivers. Background technique [0002] The navigation signal receiving device is used to receive navigation signals from satellites such as GPS satellites, and thereby measure the distance between the signal source and the navigation signal receiving device. However, in urban areas and the like, in addition to direct waves from satellites, multipath waves generated by reflections from buildings, the ground, etc. also reach the navigation signal receiving equipment. Therefore, in the navigation signal receiving equipment, it is ...
