Accurate smartphone positioning in dense urban environments remains challenging due to signal blockage, multipath effects, and unreliable satellite visibility. This study presents a new positioning ...

A novel method using signals of opportunity from Low Earth Orbit (LEO) satellites is redefining what’s possible in satellite-based navigation. Researchers have developed a joint pseudo-range and ...

Global Navigation Satellite Systems (GNSS) have revolutionised location-based services by providing positioning information through satellite signals. In urban environments, however, positioning ...

Field experiments conducted in a dense campus environment with severe signal obstruction show clear performance gains. The proposed method achieved horizontal positioning errors within 3 m and 5 m for ...
