FUSION POSITIONING SYSTEM

PolyNav 4000

PolyNav 4000 is a state-of-the-art multi-source fusion positioning system developed by PolyExplore, designed to deliver high precision, high accuracy, and outstanding cost efficiency.

Powered by PolyExplore’s next-generation multi-sensor fusion algorithm engine, PolyNav 4000 offers millisecond-level positioning response, ensuring ultra-fast and reliable performance. Its redundant multi-source architecture guarantees uninterrupted positioning—when a single signal is interfered with or lost (for instance, in tunnels or urban canyons), other data sources seamlessly compensate to maintain continuous stability and accuracy.

By integrating GNSS, IMU, LiDAR, and vision data, the PolyNav 4000 overcomes traditional environmental constraints and achieves centimeter-level or even higher positioning precision. It performs reliably even in harsh weather, obstructed environments, or weak-signal areas, effectively eliminating the limitations of single-technology positioning systems.
