ALL-IN-ONE MONITORING SOLUTION

The H3 seamlessly combines a GNSS antenna and module, a high-end MEMS sensor, and a 4G modem into one integrated system. This eliminates the need for external components beyond a power supply, streamlining field installation. The built-in MEMS sensor provides additional tilt and vibration data for comprehensive monitoring.

RELIABLE POSITIONING IN HARSH ENVIRONMENTS

Leveraging 1408 GNSS channels and CHCNAV's patented iSTAR algorithm for robust satellite tracking, the H3 delivers millimeter-level 3D positioning accuracy. Its rugged, IP67-rated design withstands harsh outdoor environments, while its low power consumption enables long-term solar-powered operation.

TIMELY RESPONSE TO DEFORMATION

Utilizing high-end MEMS components and advanced variable frequency control technology, the H3 enables rapid data uploads when sudden ground deformation is detected. This feature is critical for providing immediate warnings and overcoming the limitations of long-term static GNSS monitoring.

CHCNAV's new H3 GNSS monitoring receiver provides an all-in-one solution for reliable, accurate, efficient deformation and subsidence monitoring for industries managing critical infrastructure.
