Survey Results With Precision Stability

Surveys by sonar systems are excellent methods for tracking underwater pipelines and objects and for locating unwanted objects on the sea floor, such as mines. Such surveys are reliant on precision and high resolution to provide accurate and reliable results.

The PROSAS Surveyor is designed for pipeline tracking and underwater searches. It uses an advanced synthetic aperture sonar system to provide accurate information across the entire sweep without the distortion usually associated with objects at the outer rim of the field. It registers the geographical position of objects, allowing for subsequent surveys to relocate the object and to discover any changes or movements. It can also find new objects not found in previous sweeps, for example during port or homeland security.

Pinpointing and identifying objects lying on the sea bed require a combination of quality equipment and a stable platform. Unlike other SAS Sonar systems, the PROSAS Surveyor is based on an ROTV platform rather than an AUV. AST chose the Focus 2 ROTV by MacArtney because of its stability in the water. It provides that positioning precision needed to locate objects just inches in size across the entire sonar sweep and can be programmed to precisely follow the seabed or a pre-set path.
