Solstice is a Multi Aperture Sonar (MAS) designed for Search, Classify and Map (SCM) and Hydrographic AUV operations with integrated swath bathymetry. It has been tailored for AUV operations providing high resolution imagery that can be used for mine recognition, hydrography and post-mission analysis. The imagery produced by Solstice is designed to be of the highest quality possible from side-scan sonar. The along-track resolution of 0.15° is unrivalled.

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 only 18 Watts of power. The low power and wide swath results in long vehicle endurance and high area coverage rates. It has already been integrated with leading AUV brands.
