Batteries & Chargers
The ISS360 is the world’s most compact imaging sonar and provides an ideal solution for ROV & AUV navigation.
Navigation, obstacle avoidance and target identification for the smallest to the largest underwater vehicles. For operations requiring a higher angular resolution and range capability the ISS360 is an ideal choice.
Both the ISS360 and ISS360HD utilise a Titanium housing to enable many years of operation. The ISS360 is available in depth ratings of 4,000 meters / 13,123 feet or 6,000 meters / 19,658 feet. The ISS360HD is depth rated to 6,000 meters / 19,658 feet as standard.
Features
All ISS360 imaging sonars utilise a broadband composite transducer coupled with CHIRP acoustics to provide excellent image clarity and range capability.
The sonar provides a full 360° field of vision produced by a mechanically scanned transducer. The transducer utilises inductive coupling to the sonar electronics which enables operation without the use of slip rings. This ensures excellent longevity in operation without the need to periodically return for slip ring replacement.
All sonar settings are fully software configurable using the seaView software. The seaView sonar application is highly intuitive to use for the operator, ensuring range, resolution and other settings can quickly and easily be adjusted.
Alternatively a software development kit is available for third party integration and interface development.
The use of CHIRP (Compressed High Intensity Radar Pulse) acoustics enables the ISS360 range of Sonars to produce imagery with exceptional clarity.
The ISS360 sonar can be operated at any frequency from 600 to 900kHz. By default a 300kHz CHIRP (600 to 900kHz) is used for shorter ranges, with the bandwidth decreasing as range is extended.
The CHIRP frequency can be adjusted as required or a monotonic signalling scheme can be chosen.
The use of CHIRP acoustic signalling enables a significant increase in range resolution while maintaining an excellent range capability.
In the example above, the ISS360 Sonar image on the left is created using a single frequency pulse (Monotonic Acoustics). The ISS360 Sonar image on the right uses the same settings, but instead of a single frequency pulse, a 100kHz bandwidth CHIRP pulse is used.
Optionally available within all ISS360 Sonars is a Pitch & Roll sensing capability.
The Pitch and Roll sensing is based on Micro-Electrical-Mechanical-System (MEMS) technology.
Within the ISS360 there are three MEMS based Gyros, Accelerometers & Magnetometers. The outputs from each of these MEMS devices are fused together, providing highly stable Pitch & Roll.
