Using BDS + GPS dual system satellite intelligent fusion positioning program, which more satellites involved in the positioning solution, can satisfy the user's high precision positioning demand in various complex environments 2. Fast online calibration : After each power-up, the zero-point offset is estimated by gravity field information and single-dimensional Kalman filter, and the filter convergence is accelerated by satellite navigation information. Its on-line calibration technology does not require a special trajectory or curve in the form of a carrier, which can be calibrated while driving or riding, allowing the system to enter the combined navigation state. 3. Using tight GPS/INS integration system, in the tunnel and underground parking and other NO satellite status place is still 100% accurate positioning. 4.No need for odometer signal input, only the use of pure inertial navigation algorithm, for high-precision positioning, speed and attitude measurement on vehicle carrier in a long time. To solve the post-installed market need to access the mileage problem 5. There is no special requirements on installation angle, just try to keep it horizontal to achieve more ideal positioning effect. Adaptive algorithm can automatically identify and filter the estimated installation error angle, and compensate it. 6.Small stamp hole encapsulation, compaible with Ublox NEO encapsulated module pins 7. Can receive the difference data of the foundation enhancement network, support RTD positioning, to achieve the majority of the sub-level positioning of the scene. Pacakge Included 1 x GPS
