" conducted at urban locations across the Pacific region, we found that disabling BeiDou reduced positioning accuracy by 30% to 40% — a staggering loss of precision with significant real-world implications for navigation, logistics and emergency services.
These tests compared GPS+Galileo performance against GPS+Galileo+BeiDou in environments with limited sky visibility, where multipath interference and signal blockage are common.
While results may vary in other geographies or under open-sky conditions (and would likely improve with the inclusion of additional constellations such as GLONASS), the findings underscore BeiDou’s critical role in in real-world, urban navigation scenarios."
