INS812 is a cost-effective automotive integrated navigation system. It has a built-in high-precision satellite positioning module integrating a tactical-grade 6-axis MEMS inertial measurement unit and PPP-RTK function. It can provide real-time position and navigation in various harsh environments. Attitude and velocity information can also provide acceleration, angular velocity and other information. The product is suitable for a variety of intelligent driving application scenarios, and other features (camera, millimeter-wave radar, lidar, etc.) can be added according to customer needs to assist in achieving multi-source sensing fusion positioning.
