DDM350B / DDM360B HIGH ACCURACY DYNAMIC 3D DIGITAL COMPASS ▶ 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...

DDM350B / DDM360B HIGH ACCURACY DYNAMIC 3D DIGITAL COMPASS ▶ MEASUREMENT AND INSTALLATION Since the azimuth angle of the three-dimensional electronic compass uses the principle of geomagnetism, it is necessary to select the environmental installation location with the least magnetic interference. Please install this product away from iron, magnets, motors, and other magnetic objects. Even if there are these magnetic media around, it needs to be controlled at more than 40CM (different magnetic fields interfere with the compass at different distances). To ensure product measurement accuracy, Copper...

DDM350B / DDM360B HIGH ACCURACY DYNAMIC 3D DIGITAL COMPASS ▶ CALIBRATION METHOD 1) The accuracy of the test compass cannot meet the requirements; 2) There is magnetic interference in the compass installation environment. This interference is fixed, stable, and the distance between the interference and the compass will not change after installation (for example: the compass is installed on an iron material, because iron will interfere with the magnetic field. It is necessary to rotate and calibrate the iron and the compass together, and the iron will not be separated from the compass during use....
