product’s weight also adds to its unique features. The Titanium unit is just 0.33 kg in air or 0.225 in water, and the Delrin unit – depth rated to 1,000m – weighs less than half of this. Based on the latest in MEMS technology, the unit encompasses high grade gyroscopes, accelerometers and magnetometers. A high- ly advanced fusion algorithm is used to provide highly stable and accurate heading, pitch and roll (heading to ±0.5°, pitch and roll to 0.05°).

Operating within the SeaView software platform, or interfaced directly to a third-party system. This allows the ISM3D to eas- ily be installed in any subsea vehicle with no re-engineering of the system required.

Ben Grant, Impact Subsea Managing Director, said, “As a technology driven business, seeing our products being quickly and successfully integrated into customers underwater vehicles has been very rewarding. The ISM3D has several unique techni- cal capabilities that you can’t
