Magnetic Compass

  • The HSC603 electronic magnetic compass features high precision, small size, and low power consumption. By using geomagnetic field directivity to measure space attitude angle, the product can measure three-dimensional attitude information: azimuth, pitch, and roll angle. The self-developed magnetic interference calibration algorithm can obtain the best measurement via two-dimensional or three-dimensional calibration. It can be widely used in a variety of scenarios in which the user needs to obtain the attitude angle of platform (or carrier), such as with autonomous underwater operations, land-based orientation, flight attitude measurement, and so on.


  • The magnetic compass provides several advantages, including its small overall size, low power consumption, high precision, and wide tilt range. The working current of 7mA is also suitable for situations with precise requirements for angle accuracy, as well as cases where power consumption and volume are limited. It is highly suitable for today's miniaturized military high precision attitude measurement integrated control system.
