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 ...

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 ...

Researchers from the Aerospace Information Research Institute, Chinese Academy of Sciences, have pioneered a combined pseudo-range and Doppler positioning method that leverages signals from ...

Researchers are taking experimental navigation technology to the skies, pioneering a backup system to keep an airplane on course when it cannot rely on global positioning system satellites. Dangling ...

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 ...

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 ...
