INDOOR-OUTDOOR DUAL-USE HIGH PRECISION POSITIONING SYSTEM

摘要

Outdoor positioning for a plurality of mobile terminals (20) is performed using an indoor positioning system including a plurality of base stations (10), by installing the plurality of base stations on respective outdoor locations in an outdoor area, where the base stations are configured to use a predetermined communications link for indoor positioning at indoor locations, performing independent precise positioning at each of the plurality of base stations using a plurality of GNSS signals, thereby determining a precise position of the outdoor location of each base station without surveying or measuring the installed location thereof, and performing outdoor positioning of the plurality of mobile terminals in the outdoor area using the determined precise position of each of the plurality of base stations in a same manner as the indoor positioning, by receiving, at the plurality of base stations, signals from the respective mobile terminals via the predetermined communications link.
