The Sonavision range of scanning sonar’s provide unsurpassed acoustic performance and scanning speed as well as being robust, accurate and corrosion resistant. They can operate from moving platforms, such as ROV’s or fixed platforms such as seabed tripods. Scanning Sonar’s for Obstacle Avoidance Scanning Sonar There are three sonar models in the range, SV1010, SV2020 and SV4040. Each sonar has an acoustic transducer which rotates through a predetermined angle and then transmits a short acoustic burst at a specified frequency. Echoes or reflections are produced by any object in the path of this burst transmission and the time between transmit and receive is used to measure the range to the object. All echoes are plotted on a PPI (plan position indication) display which may be used for navigation, location and sizing of any target within range. The transducer has a predefined “fan” beam pattern with a very narrow horizontal angle providing high angular resolution and a much wider vertical beam angle which minimises the risk of missed targets above or below the central axis, when used for obstacle avoidance. Control Unit Display Common applications for Sonavision sonar units, when ROV or AUV mounted, are obstacle avoidance, navigation and target identification / sizing. The SV range sonars are suitable for use on all sizes vehicles from AUV to large working class ROVs. The sonar’s are provided with a Windows compatible control and display software application. The software can be configured to display the sonar data in four different ways dependant on the use of the sonar. The package provides full control of the sonar characteristics including operating frequency, range, scanning speed, scanning angle and many other useful adjustments. The application runs on Windows PCs as well as embedded versions running on industrial and rack mounted PC’s.

Applications A wide range of variety • ROV Navigation • Mine Classification • AUV • Obstacle Avoidance • Target Identification • Diver Monitoring In general the Sonavision SV range of sonars are used in a wide range of different applications. Due to the compact design and high performance of the Sonavision sonar’s have led to several applications for example in the military. These include hand held configurations for divers, mine identification from small ROV’s and installation within swimmer delivery vehicles, where the sonar provides real time display of the underwater environment and...

New Generation SV series Evolution of the proven Sonavision product family SV1010 The SV1010 is the smallest unit in the family, particularly suitable for small ROV applications where it offers an extremely high resolution performance with good range capability. An oil filled hood protects the transducer and motor drive components. Frequency of operation is user selectable within the range 600kHz to 1200kHz. The SV1010 is also available in a 300m rated acetal housing which provides a reduced weight option for use on smaller vehicles. ••Exceptionally compact size ••High resolution ••Mid to...
