DDM350B&DDM360B HIGH ACCURACY DYNAMIC 3D DIGITAL C...

Product Description:

DDM350B / DDM360B is a three-dimensional dynamic electronic compass, which integrates a 9-axis inertial measurement unit, including a three-axis accelerometer, a three-axis gyroscope, and a three-axis fluxgate. Utilizing the high dynamic angle characteristics of the gyroscope and the highly stable attitude characteristics of the accelerometer, the pitch and roll angles that follow the complex attitude changes are obtained through the dynamic inertial navigation algorithm. The geomagnetic azimuth angle adopts hard magnetic and soft magnetic calibration algorithms, so that the compass can eliminate the influence of the magnetic field through the calibration algorithm even in the environment with magnetic field interference. The heading is calculated in real time by the central processor, and the dynamic pitch and roll angles are used for dynamic heading compensation for a wide range of magnetic azimuths, ensuring that the compass can provide high-precision heading data even at tilt angles of up to ±85°. The electronic compass integrates a high-level DSP arithmetic processor with diversified output modes. The standard interfaces include RS232/RS485/TTL and other interfaces, and other communication interfaces can be customized.
