Impact Subsea – ISM3D AHRS Unit

Introducing the ISM3D

The ISM3D is a highly accurate underwater Attitude & Heading Reference System. The ISM3D utilises high grade MEMS based Accelerometers, Angular Rate Gyroscopes and Magnetometers all of which feed into an advanced fusion engine driven by a dual core micro-processor. The unit provides Heading to ±0.5° of local Magnetic North with Pitch and Roll to ±0.07° accuracy. Provided in a Titanium housing, depth rated to 6,000 meters, with a length of 65mm – the ISM3D sets a new standard in size, durability and capability. Also available in an Acetal Housing depth rated to 1,000 meters or as an OEM system.

Heading

Heading to ±0.5° of local Magnetic North. The Heading is derived from Micro-Electrical-Mechanical-System (MEMS) based technology. Within the ISM3D there are MEMS based Gyros, Accelerometers & Magnetometers. The outputs from each of these MEMS devices are fused together using an advanced fusion algorithm. The output from this is highly stable Heading, Pitch & Roll.

Pitch & Roll

Pitch & Roll to ±0.07° Accuracy.

The Pitch and Roll reading is derived from Micro-Electrical-Mechanical-System (MEMS) based technology.

Within the ISM3D there are three MEMS based Gyros, Accelerometers & Magnetometers. The outputs from each of these MEMS devices are fused together, providing highly stable Heading, Pitch & Roll.
