The H3 is a cost-effective and versatile GNSS smart receiver leveraging CHC Navigation's expertise in subsidence and deformation monitoring for critical infrastructure such as dams, bridges, and landslide-prone areas. Unlike traditional GNSS monitoring systems, the H3 features an intelligent antenna design that achieves a high level of integration. This design includes the GNSS antenna and module, a low-power interface board, multiple communication modules, and MEMS in a compact, all-in-one unit. The H3 provides reliable data for both long-term static positioning and dynamic positioning, making it a prime and efficient solution for demanding monitoring applications.
