DDM365B is a three-dimensional dynamic electronic compass that integrates a 12 axis inertial measurement unit, including three-axis attitude angle, three-axis accelerometer, three-axis gyroscope, and three-axis magnetic induction technology. By utilizing the high dynamic angle characteristics of gyroscopes and the high stability attitude characteristics of accelerometer, the pitch and roll angles that follow complex attitude changes are obtained through dynamic inertial navigation algorithms. The geomagnetic azimuth angle adopts hard and soft magnetic calibration algorithms, which enable the compass to eliminate the influence of magnetic fields through calibration algorithms even in environments with magnetic field interference. By real-time calculation of heading through the central processing unit and dynamic heading compensation of magnetic azimuth over a large range using dynamic pitch and roll angles, the compass can provide high-precision heading data even at a tilt angle of up to ± 85 °. The electronic compass integrates a highly DSP processing unit with diverse output methods, including standard interfaces such as RS232/RS485/TTL, and can also accept customization of other communication interfaces.
DDM365B is small in size, low in power consumption, and can be used in many highly seismic and extremely harsh environments such as offshore ships, antenna search, etc. It is more suitable for various high-precision measurement integrated control systems today.
