FSS-NAV680D Introduction: FSS-NAV680D is a multi-sensor integrated navigation product launched by Forsense Technology based on the vehicle-grade IMU platform and the full-system full-frequency dual-antenna RTK. NAV680D has a built-in high-precision IMU module of Forsense and supports external odometer information, thereby providing accurate, continuous and real-time attitude, speed and position information in scenarios such as urban canyons, tunnels and viaducts. Volume: 116*85.9*32mm Weight: 263g Application fields: High-precision scenarios such as passenger cars, commercial vehicles, engineering vehicles, and inspection vehicles. Product features: (1) Built-in high-precision RTK board card of full-system and full-frequency, supporting BDS B1/B2/B3 + GPS L1/L2/L5 + GLONASS L1/L2 + Galileo E1/E5b. (2) Built-in high-precision IMU module of Forsense. Through a perfect integrated navigation algorithm and space-time synchronization mechanism, it provides real-time and accurate attitude, speed and position information. (3) Supports internal storage of log data. (4) Supports recording RTK raw observation data and ephemeris. (5) Supports external odometer. Software interface: Serial port, CAN Hardware interface: RS232, CAN(A), CAN FD(B), network port, GNSS antenna interface, power interface, PPS interface.
