The CHCNAV Apache 3 Pro is a compact, autonomous unmanned surface vehicle designed for bathymetric surveys in shallow water environments. Weighing just 6 kg and operable by a single person, it deploys rapidly on rivers, lakes, reservoirs, and canals where larger vessels cannot operate. Integrated GNSS RTK and INS navigation maintains precise positioning even when satellite signals are blocked - under bridges, along urban waterways, and in confined channels - while the CHCNAV D270 single-beam echosounder delivers depth accuracy to within 1 cm.
