key word: MS-6222 High precision MEMS integrated navigation system
Details
MS-6222 is a high-precision MEMS combined navigation system independently developed by LINS Technology. It has built-in self-developed high-precision MEMS IMU (inertial measurement unit) and self-developed high-precision dual- antenna GNSS module. It adopts multi-source Kalman filter fusion algorithm, which can provide continuous and reliable high-precision positioning and navigation information in complex environment.
The products are widely used in satellite communication, UAV, surveying and mapping, stability platform and other fields.
Main features:
