Key Advantages & Technical Specifications
One of China's first commercially deployed magnetic positioning solutions · military-grade technology transferred to civilian use, validated by multiple national-level awards
🏆 Key Advantages
| Fully passive | Senses only the geomagnetic field and emits no signal — covert, zero radiation, privacy-safe |
| No construction | Uses the building's inherent magnetic characteristics — no base stations or beacons to install, just one fingerprint survey |
| Maintenance-free | No hardware requiring periodic inspection — operating costs near zero |
| Floor recognition | Distinguishes floors from vertical magnetic field characteristics, with automatic multi-floor switching |
| Obstruction-immune | Strong magnetic penetration — unaffected by walls, people or metal shelving |
| Full-area coverage | Works in every GPS-denied area: underground utility tunnels, mines, tunnels, large venues and more |
| EMI-resistant | The geomagnetic field is stable — unaffected by multipath effects, electromagnetic interference or crowd occlusion |
| Low-power terminal | Terminal power < 200mW, continuous operation 24h+ |
