Solstice is a search and classify AUV side scan sonar with integrated swath bathymetry that has been designed for small, medium and large AUVs for the provision of high resolution imagery that can be used for mine recognition and post-mission analysis. The imagery produced by Solstice is designed to be of the highest quality possible from a conventional (non-SAS) sonar and works best when deployed between 7 and 10 metres above the sea bed.

The sonar has been carefully designed so that it will give excellent results even in very shallow water, where other side scans suffer degradation due to multi-path effects. All of which is achieved whilst consuming typically only 18 Watts of power. The low power and wide swath results in long vehicle endurance and high area coverage rates.
