Product Details

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


High Stability MEMS Inertial/Satellite Integrated Navigation System is equipped with micro MEMS gyroscope, accelerometer, and mobilesurveying and mappinglevel multimode multi frequency GNSS receiver which supports GPS/GLONSS/BD function. After careful design, the system size with excellent integrated navigation performance can be reduced to an unprecedented compact, which can achieve dynamic rapid alignment or GNSS dual antenna aided rapid and high-precision orientation, and the directional 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.

Product supportsGNSS/ odometer /DVL/ barometric altimeter and other external sensors, 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, whileit also hasAHRS 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.
