GNSS Inertial Navigation System
INS821
INS821 is a high-precision automotive integrated navigation system. It has a built-in high-precision satellite positioning module integrating tactical-grade 6-axis MEMS inertial measurement unit and PPP-RTK function. It is equipped with a higher-precision IMU module and can operate in various harsh environments. Provide real-time position, attitude, speed information, acceleration, angular velocity and other information. The product is small in size, light in weight, and cost-effective. It is suitable for intelligent driving application scenarios such as passenger cars, Robotaxi, Robotruck, port logistics vehicles, and mining area engineering vehicles. Other features (camera, lidar, etc.) can be added according to customer needs. ) assists in realizing multi-source sensing fusion positioning.
