Description

Solstice is a Multi Aperture Sonar (MAS) designed for Search, Classify and Map (SCM), Mine Counter Measures (MCM) and hydrographic AUV operations with integrated swath bathymetry. It has been tailored for AUV operations providing ultra-high resolution imagery both across and along the track of the AUV. With an along-track resolution of 0.15°, the imagery produced by Solstice is considered to be of the highest quality possible from a side-scan sonar. It offers full dynamic focus across a wide area, 200 metre swath. The images are designed to be of the highest quality possible from side-scan sonar. Solstice aids vehicle operators make better decisions and improves results from Computer Aided Detection and Classification (CAD/CAC).
