The SSU003 - is a compact Hydra™ series mechanical all-around drive kit, used for  operation of a side-scan sonar (SSS) in the sector mode or all-around mode (ALS)  when operating on  ice (through a hole) as well as on motionless bases.
The kit is an auxiliary equipment that functionally complements and expands the capabilities of the Hydra™ complex.
The drive is a device operating under the control of the program HyScan (hereinafter HS), and controls the speed and direction of rotation of the electric motor of the drive. HS sets the operating mode of the drive, the speed of rotation, the direction of rotation, the rotation sector, and the drive generates for HS the current angle of position and the current state.
It is used when shooting the surface of the bottom of the water area under the ice and under stationary objects (platforms, crossings, etc.).  
The drive is controlled via the RS485 interface, the drive is connected to a PC compatible laptop with the Microsoft ®Windows® operating system to the USB port via the RS485/USB adapter included in the kit. The HS program is included in the delivery kit of the sonar.
With the help of all-around looking sonar (ALS), it is effective to carry out works on diagnostics of underwater crossings, to carry out inspection of mooring walls, bridge supports, piles, to control underwater laying of the pipeline in the trench. ALS can be used in conditions where it is impossible to use SSS for reasons of shallow depth, cramped conditions that do not allow the movement and maneuvering of the vessel, as well as in winter conditions. 

Areas of application:

• search for objects from ice;
• engineering and ecological monitoring;
• scientific projects (geological, archaeological, ecological, etc.).

Features:

• work from ice or fixed platforms;
• small size and weight;
• powered by widespread rechargeable batteries.
