Research on the Recognition of the Inland Ship Motion Status under the Stopping and Low-Speed Sailing Condition

Due to interferences and some other reasons, the GNSS(global navigation satellite system) module in AIS would provide fault information, it is difficult to distinguish whether is the vessels are stopping or low-speed sailing without the help of Kalman filter algorithm. This paper has proposed a method to handle the error in GNSS information in AIS messages, which turns out to be effective in the experiment.
