In order to provide for the safe and expeditious passage of maritime traffic in congested waters, the U.S. Coast Guard is authorized by the Ports and Waterways Safety Act to establish, operate, and maintain Vessel Traffic Services (VTS) where needed. In larger areas, a VTS will generally require a communication system to enable the vessel traffic center and the participating vessels to exchange information. VORA (VTS system for Operator's Rapid Situation Awareness) is a maritime traffic monitoring system which provides a comprehensive representation of vessel traffic situation to operators. VORA uses radar, CCTV, VHF/DSC, VHD/DF, SCADA, weather sensors, AIS to keep track of vessel movements and provide navigational safety, safety of life at sea and the protection of the marine environment in a limited geographical area. VORA consists of hardware and software components which collect, integrate, analyze and display data. In this paper, we introduce the redundancy method of VORA subsystem, MSIS (Multiple Sensor Integration System). This is related to the redundancy method, including data redundancy. The data redundancy role is up to each subsystem policy. Experiments show that though if MSIS is in the error case, MSIS with the supposed redundancy can provide the continuous service.
