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 ...

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 ...

Satellite-based positioning, a cornerstone of modern geospatial technology, relies on a constellation of orbiting satellites to provide precise geolocation and timing information to receivers ...

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 ...

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 ...

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 ...
