Most accurate and stable gyro-stabilised compass module

Acal BFi now stocks the new Honeywell HMR3601 precision gyro-stabilised compass module for the European market. Offering high accuracy and stability, the 3-axis digital gyro-stabilised compass module has azimuth accuracy of 0.5 degrees with 0.1 degree resolution, a +/-80 degree pitch and roll range, and < 0.5 degree tilt accuracy. The HMR3601 features novel gyro stabilisation, combining three magneto-resistive sensors, three MEMs accelerometers and a MEMS yaw rate gyro to provide for hard and soft-iron correction algorithms, reducing the effect of magnetic disturbances and keeping the heading output accurate. With its fast update speed and rugged construction, this azimuth sensor is suitable for a range of applications including antenna pointing, weather station heading, UAV/AUV heading, and target locator heading, says the company. Martin Kemp, European business development director, sensors, Acal BFi, said: “We are pleased to introduce Honeywell’s HMR3601, their most accurate and stable compass module, to the European market. The addition of this high accuracy azimuth sensor greatly adds to Acal BFi’s current sensor portfolio and enhances our ability to provide our customers with the most innovative and high quality sensors on the market.”
