Small size USV system ALPHA ARK S for underwater survey
Alpha ARK-S is a compact V-shaped trimaran boat which is made of high-strength Kevlar & carbon fiber composites material,making the boat lightweight, shock proof and highly tough. Alpha ARK-S is able to carry different sensors to perform a variety of tasks according to demand and easily cope with a variety of complex operating conditions.
Strong resistance to impact & high correction resistance
Smart control system
Autonomously performing collection missions according to the planned route,and real-time adjustment of navigation attitude with the help of water flow adaptive adjustment system.Multiple control modes can be switched with one button to easily cope with various operating conditions.
Accessible communications
Real-time RF point-to-point communication,barrier-free data transmission, meeting various operating environments.
Inbuilt high-precision GNSS module
Alpha ARK-S navigates with a built-in GNSS module which can provide high-precision position, making underwater measurements more accurate without carrying additional GNSS equipment, easy of one-man operation. comprehensive ensure navigation and equipment safety.
Safety protection mechanism
Worry-free protection of automatically return after completing the preset missions or lost communication, or the battery is in low voltage, which comprehensive ensure navigation and equipment safety.
