MEMS Inertial Navigation System

Product description:

This product is equipped with micro MEMS gyroscope, accelerometer, and mobile surveying and mapping level 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° .

Product supports GNSS/ 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, 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.

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.
