Comparison Between Information Provided by Radar and AIS in The Integrated Vessel Traffic Systems

Abstract

The present paper contains comparison between the oncoming information from shore based radar and AIS in the integrated vessel traffic management and information system of Bulgaria (VTMIS). The experiments are based on using records of real traffic from the coverage area of the system. Comparison between positions, courses and speeds of moving and anchored targets provided by the radar and AIS subsystems respectively, are presented in this paper. The accuracy of both data is estimated and compared with the accuracy required by IALA.
