M-type trimaran boat shape USV system Alpha ARK for underwater survey
Alpha ARK is made of Kevlar & carbon fiber composites with a M-type trimaran boat shape which has strong resistance to impact. lts closed-cell foam filling and fully enclosed compartments are anti-sinking and waterproof design. The modular design is easily assemble and disassemble all parts for maintenance. Alpha ARK equip with different sensors to perform a variety of tasks according to demand and easily cope with a variety of complex operating conditions with multiple security protection mechanisms!
Great ability against wind and waves & excellent seaworthiness
Multiple safety protection mechanisms & safe navigation
Alpha ARK monitor the operational status of the USV in real-time by the 360 ° full view camera, no longer need to worry about obstacles encountered during navigation for the ultrasonic obstacles avoidance module can help timely and effectively avoid obstacles, and no longer need to worry about communication loss due to the multiple low-voltage and safe return mechanisms to ensure navigation safety.
Two modes of communication & celerity and accuracy in data control
Standard bridge and network communication modes meet the needs of a variety of working conditions, and get rid of transmission distance restrictions. The multi-link ensure stable data transmission to keep accurate data at hand.
Powerful battery & long endurance
Its intelligent lithium battery supports for fast charging and discharging, the system is equipped with self-protection function including battery explosion-proof bag and specially waterproof dealing. The powerful battery and low consumption supports 6 hours of endurance under economic condition.
Strong resistance to impact & high corrosion resistance
The hull is made of Kevlar & carbon fiber composite material in acid, alkali and corrosion resistance, which is lighter in weight, strong in impact resistance, good in sealing. Its remarkable hull design is convenient for transmission and reliable placement.
