Provides Heading to ±0.5° of local Magnetic North with Pitch and Roll to ±0.05° accuracy.
The high update rate (up to 250Hz) is highly applicable for use with auto heading and vehicle stabilisation systems.
For optimal performance, a hard and soft iron calibration can be performed on the unit once installed on the ROV or AUV. This ensures that a consistently accurate heading is provided at all times.
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.
