When 5G networks bolster satellite navigation

Tokyo, Japan (SPX) Dec 26, 2025 Finding accurate positions in dense urban areas remains difficult for satellite-based navigation systems, where high-rise buildings and signal blockages can cause large errors or complete loss of service. A recent study outlines a deeply integrated positioning method that combines commercial 5G New Radio (NR) signals with Global Navigation Satellite Systems (GNSS) to address these issues. By rei

Cities Without Blind Spots Global navigation satellite systems sit quietly behind almost every modern positioning service, from smartphones and fleet tracking to surveying and construction automation. Their limits, however, are well known. Dense city centres, high-rise developments, tunnels, flyovers, and tree-lined streets all conspire to weaken satellite visibility. Signals bounce, diffract, or vanish altogether. Under such conditions, even ad…
