Application of GIS-aided INS/GNSS/GPRS navigation technology in logistics

Aiming at the problem of effective transportation in high-precision logistics, this paper adopts global navigation satellite system, general packet radio service and inertial navigation technology to construct an integrated navigation system within GIS-aided, and designs a federal filter structure with adjustable information allocation coefficients to get navigation solving. To eliminate the observation anomaly, the DBSCAN clustering algorithm is used to evaluate the performance of the measurement information and serve as the basis for setting the adjustment information allocation coefficient, which can effectively improve the contribution of the local optimal estimation of the integrated navigation system and optimize the global evaluation. The geographical information can be used to avoid congested road sections in real time to improve the efficiency of logistics transport and distribution. Finally, simulation results shown that the integrated navigation system proposed and the designed federal filter structure can effectively improve the navigation and positioning accuracy of the vehicle, and improve the stability of the system in the case of limited satellite signal reception. The horizontal position accuracy of the logistics vehicle is controlled within plus or minus 3m.
