12 axis 3D Digital Electroninc Compass Sensor For Antenna Servo Control
▶ Product Introduction
DDM365B is a three-dimensional dynamic electronic compass with a 12-axis inertial measurement unit, including a three-axis attitude angle, a three-axis acceleration meter, a three-axis gyroscope, and a three-axis magnetic induction technology. Using the high dynamic angle characteristics of the gyroscope and the high stability of the attitude characteristics of the accelerometer, the pitch angle and roll angle that follow the complex attitude change are obtained by the dynamic inertial navigation algorithm. The geomagnetic azimuth adopts hard magnetic and soft magnetic calibration algorithms, so that the compass can also eliminate the influence of the magnetic field through the calibration algorithm in the environment with magnetic field interference. Through the real-time heading calculation of the central processing unit, and the dynmic heading compensation of the magnetic azimuth in a wide range by using the dynamic pitch angle and roll angle, the compass can provide high-precision heading data even at the tilt angle of up to ±85°. The electronic compass integrates a high DSP computing processor, and the output mode is diversified, among which the standard interface includes RS232/RS485/TTL and other interfaces, and can accept the customization of other communication interfaces.
DDM365B small size, low power consumption, can be applied to many high seismic resistance, extremely harsh environments such as marine ships, antenna star search, etc., and is more suitable for today's various high-precision measurement integrated control systems.
