Introduction: Why GNSS Precision Matters in Urban Traffic Surveillance
In today’s rapidly advancing era of modern urban intelligent transportation systems, drones have become essential tools for all-weather, three-dimensional traffic monitoring. However, as surveillance tasks shift from macro-level observations to micro-level vehicle trajectory tracking and accident reconstruction, limitations in traditional GNSS modules become increasingly apparent.
Why the Septentrio mosaic-X5 GNSS Receiver Solves Urban Monitoring Pain Points
The Septentrio mosaic-X5 GNSS module is engineered to overcome the specific challenges of urban aerial monitoring environments, providing anti-interference, multipath suppression, and centimeter-level accuracy.
Born for Urban Three-Dimensional Space
The compact 31×31×4 mm module integrates 448 hardware channels and supports all global satellite systems—GPS, GLONASS, BeiDou, and Galileo—ensuring stable positioning even in obstructed, reflective, or high‑interference conditions.
