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.
Product Detail
Strong resistance to impact & high correction resistance
Alpha ARK-S is made of Kevlar & carbon fiber composites material in acid, alkali and correction resistance, which is lighter in weight, strong in impact resistance good in sealing. lts remarkable hull design is convenient for transmission and reliable placement.
-
Safety protection mechanismWorry-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. -
Inbuilt high-precision GNSS moduleAlpha 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. -
Accessible communicationsReal-time RF point-to-point communication,barrier-free data transmission, meeting various operating environments. -
Smart control systemAutonomously 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.
Available Instrumentation
APPLICATIONS
ADCP section velocity measurement
Traditional cross-section measurement requires the use of bridges to measure fixed cross-sections, or renting manned boats to measure on river cross-sections. However,the use of unmanned boats equipped with corresponding ADCP device for fully automatic measurement, which does not require being limited to fixed locations or manual measurement.With the help of high-precision navigation system, as traighter cross-section measurement line can be achieved than manual measurement,ensuring that each measurement is on the same cross-section measurement line,greatly improving data accuracy;
Mapping of underwater topography and geomorphology
The unmanned boat equipped with a small-size and lightweight single-beam echo sounder, which has strong maneuverability. You can start the deployment operation as soon as you arrive at the site. Planning the route and set it automatically pilot according to the terrain mapping scale,and detect real-time water depth data and bottom elevation. Using the USV can effectively solve the pain points of traditional manual aboat rental,installation, debugging, and measurement affected by terrain conditions
