    ER-MINS-5651 High Stability MEMS Inertial/Satellite Integrated Navigation System 


    High Stability MEMS Inertial/Satellite Integrated Navigation System is equipped with micro MEMS gyroscopeaccelerometer, and mobile surveying and mappinglevel multimode multi frequency GNSS receiver. It supports GPS/GLONSS/BD function. The product has excellent integrated navigation performance, and the system size can be reduced to an unprecedented compactness. It can realize dynamic fast alignment or GNSS dual antenna assisted fast and high-precision orientation, and the orientation accuracy can reach 0.1°.

    In order to meet the application demand of mobile street view mapping, ocean mapping and other mapping areas, with the original data storage and surveying and mapping level navigation post-processing software, users can choose according to requirements.

    The product supports GNSS/odometer/DVL/barometric altimeter and other external sensors, which has excellent scalability. By using multi sensor data fusion technology integrates multi-source data, the system of regional adaptability and robustness has been greatly improved, while it also has AHRS navigation reference function. In the absence of any external assistance, it can achieve long time attitude and heading keeping. It is especially suitable for unmanned aerial vehicles, underwater vehicles and other unmanned aerial vehicle navigation and attitude determination.
