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.
The Heading is highly resilient against temporary magnetic interferes. This is aided by a soft and hard iron calibration feature once the unit has been installed on the ROV, AUV or other underwater platform.
In areas where a large amount of steel of other magnetic disturber is present, the unit can be set to operate using the Angular Rate Gyroscopes and Accerometers, without input from the Magnetometer. The low drift rate of the advanced MEMS based Gyroscopes enables navigation to be conducted in areas where previously only a fibre or ring laser diode based heading sensor would suffice.
Pitch & Roll
Pitch & Roll to ±0.05° 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.
