China Launches 11-Satellite System for High-Accuracy Navigation

3/30/2026

Summary

Story summary

Chinese researchers developed an 11-satellite network for a high-accuracy optical navigation system to provide positioning where Global Positioning System (GPS) is unavailable or disrupted.
The system uses coded light signals from satellites, similar to ancient sailors navigating by lighthouses.
The project is led by Xing Fei from Tsinghua University.
It could enhance navigation for next-generation drones and other vehicles.
The optical system reduces interference because of its narrow light beams.
