Cost-effective Integrated Navigation System GI320 Introduction GI320 adopts loose coupling integrated navigation technology, which deeply integrates IMU with RTK solution and observation preprocessing, and can provide real-time and high-precision navigation parameters such as position, speed and attitude. The integrated navigation algorithm uses the GPS data as initial data for operation. If GPS data is lost, the system will run the strapdown inertial navigation calculation alone, and the calculated data will be sent to the Kalman filter for processing.

Cost-effective Integrated Navigation System GI320 Command configuration Annex 1: Configuration instructions Bewis sensor high-precision integrated navigation input command supports simplified ASCII format. The simplified ASCII format without parity digit is more convenient for user's command input. All commands consist of a command header and configuration parameters (the parameter part can be empty, then the command has only one command header), and the header field contains the command name or message header. Common commands are shown in the following table: Command config 115200...
