FSS-NAV618DPRO is a multi-sensor integrated navigation product based on industrial IMU platform and full system multi-frequency dual antenna RTK.NAV618DPRO has a unique array IMU sensor built into the Forsense Company, which supports external odometer information to provide accurate, continuous and real-time posture and velocity location information in urban canyons, tunnel elevations and other scenarios. Provides records of RTK original observations combined with IMU sampling mechanism of space-time synchronization, which facilitates high-precision post-processing for users. Convenient and diverse ways to import differential data, supporting differential data from mobile phone Hotspots or external 4G modules.
