product description:

FSS_NAV680D is a multisensor combined navigation product launched by Forsense   Technology based on the automotive_grade IMU platform and full_system full_frequency dual_antenna RTK. NAV680D is equipped with_Forsense's high_precision IMU module and supports external odometer information, thus providing accurate, continuous and real_time attitude, speed and position information in scenes such as urban canyons, tunnels and elevated roads.


Features:

(1) Built in full system fullfrequency high_precision RTK board, supporting BDS B1I/B2I/B3I; GPS L1/L2/L5; GLONASS G1/G2; Galileo E1/E5a/E5b; QZSS L1/L2/L5.

(2) High precision with built in primary electrode IMU model, through a complete combined navigation algorithm and time_space synchronization mechanism, it provides realtime and accurate attitude, speed and position information.

(3) Support internal storage of log data.

(4) Supports recording of RTK raw observations and ephemeris.

(5) Support external odometer.
