The CHCNAV H3 is an integrated GNSS monitoring receiver for dams, bridges, hydropower plants and landslide-prone areas, supporting long-term static and dynamic positioning.
Full GNSS tracking and a 3-axis MEMS sensor combine with the iSTAR algorithm to provide reliable positioning data for demanding infrastructure monitoring applications.
Its all-in-one design integrates the GNSS module, antenna, communication modules and sensors, simplifying installation and reducing system complexity.
Stated post-processing precision reaches 0.3 cm horizontally and 0.5 cm vertically under specified conditions, supporting detailed deformation monitoring.
Integrated 4G LTE, an RS232 interface and support for TCP, MQTT and NTRIP protocols enable flexible communication and monitoring data management.
A low-power design supports continuous long-term operation. IP67 protection and operating temperatures from −40°C to +65°C provide durability in challenging environments.
