The application integrates dual positioning technology: it uses GPS for wide-area route guidance in outdoor environments; and when users enter buildings, exhibition halls, or basements, the system seamlessly switches to a precise indoor positioning mode. By reading high-density Beacon (Bluetooth beacon) signals deployed in the area, it effectively solves the problem of traditional maps causing indoor navigation errors, providing users with an uninterrupted, step-by-step navigation experience from outdoors to indoors.
