Alpha M3 Patrol & Detection USV
Alpha M3 integrates high-precision BeiDou positioning and orientation, a single-beam echosounder and intelligent vessel control into one system for autonomous mission planning. It carries a 360° HD zoom camera, mobile network, radio link and millimetre-wave radar for obstacle avoidance.
It can be fitted with a dual-array side-scan sonar (35 m per side, up to 70 m total), searchlight, loudspeaker and strobe warning light, with optional night vision, thermal infrared and the DiMap CC control centre platform. The echosounder measures from 0.2 m to 120 m, so it operates confidently in shallow water.
Applications include underwater surveying, emergency detection, drowning search and rescue, engineering structure inspection, illicit outfall investigation and integrated monitoring of rivers, lakes and reservoirs. The control software plans routes automatically, resumes missions after interruption, returns home automatically and displays depths in colour.
