Internet of Vessels high-precision navigation positioning integrated equipment research

Abstract

The research of Internet of Vessels high-precision navigation positioning integrated equipment analyzes the integration problem of ship navigation equipment system, fuses and processes AIS and radar ship travel trajectory information to enable ships to travel safely in complex maritime environment, and solves the problems of low navigation positioning accuracy and limited detection capability. Kolmogorov-Smirnov test, Gauss-Kruger projection and other methods are used to solve the problems of outlier removal, coordinate unification and distance correlation judgment derived from the fusion of AIS and radar information. The simulation results of the ship travel trajectory fusion algorithm for AIS and radar indicate that the radar and AIS information can be highly fused, solving the problem of large errors in the process of radar and AIS target trajectory fusion.
