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 ...

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 ...

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 ...

There’s so much discussion around automated vehicles in the mainstream press these days, that it’s easy to forget some of the critical enabling technology needs to mature significantly before large ...

provide some protection against interfering signals. Although quantitative measures of resistance to RF interference, such as jammer-to-signal ratio (J/S) measured in decibels (dB) do exist, these ...

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 ...
