In a research article recently published in Space: Science & Technology, researchers from Chinese Academy of Military Science, Tsinghua University, and Beihang University together work on how to ...

(MENAFN- EIN Presswire) EINPresswire/ -- Accurate smartphone positioning in dense urban environments remains challenging due to signal blockage, multipath effects, and unreliable satellite visibility.

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 ...

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 ...

The proposed framework tackles urban positioning errors at both the spatial and temporal levels. First, the researchers enhanced traditional shadow matching by introducing time-differenced carrier ...
