FSS-NAV618 is amulti-sensor integrated navigation product based on industrial IMU platform andmulti-system multi-frequency RTK. NAV618 has a unique array IMU sensor builtinto Forsense, which supports external odometer information to provideaccurate, continuous and real-time posture and velocity location information inurban canyons, tunnel elevated and other scenarios.Provides records of RTKoriginal observations combined with IMU sampling mechanism of space-timesynchronization, which facilitates high-precision post-processing forusers.Convenient and diverse ways to import differential data, supportingdifferential data from mobile phone Hotspots or external 4G modules.
