MAS vs SAS – When should we use multiple aperture sonar?

Why is Solstice different from other side scan sonars? Solstice is a Multi Aperture Sonar (MAS) which functions like a top performing traditional side-scan sonar but it is processed very differently. In this approach, the multi-beam input from 32 elements is dynamically focused to extend the focus along the whole length of the swath. By …

The science behind BlueComm

Author: Matthew Kingsland – Communications Application Engineer Why Is BlueComm Blue? The general rule of thumb is whatever colour the water appears, that is the colour which will be least absorbed. Blue in clean water is the least absorbed electromagnetic wavelength, making it the obvious colour the lights in BlueComm should be using. But what …

Why Optical Comms?

Author: Matthew Kingsland – Communications Application Engineer Water is an incredibly hard medium to communicate through. In air we are all used to having almost unlimited data in our pockets and being able to stream the latest YouTube cat video at a moment’s notice. However go just a few metres underwater and all that stops. …
