Introduction
The TD-BMR3000 high-accuracy electronic compass is composed of an industrial-grade single- chip microcomputer with high reliability and anti-interference ability, and a high-accuracy magnetic sensor and driver chip. At the same time, it integrates the hard magnetic and soft magnetic calibration algorithms and compensates the tilt angle with a three-axis accelerometer, which can provide accurate heading data in extremely harsh environments. Through the optimized extended Kalman filter algorithm, the product outputs high-accuracy attitude information in real time.
The TD-BMR3000 is specifically designed to improve the static measurement accuracy of magnetic compasses. For fixed interference, it can still maintain high measurement accuracy. It can be customized according to customer requirements, and it is very convenient and quick to integrate the electronic compass function into various products.
