AIS Vessel Collision Avoidance System

AIS vessel collision avoidance system is a shipborne multifunctional system fully conforming to international and national standards. It has basic AIS functions and GPS positioning capability. Also, the AIS vessel collision avoidance system is designed with electronic chart display function. The chart display utilizes different color configurations for daytime and nighttime operations. In addition to the basic navigation and collision avoidance functions, the AIS vessel collision avoidance system provides audio and visual alarms as well. It also supports marker operations, voyage tracks and waypoints recording and voyage planning function.

In addition to above, the vessel collision avoidance system can also display the total number of received vessels and related information in a list. The communication is achieved via CSTDMA or SOTDMA protocols, which can be switched according to the base station command. The compact and light weight vessel collision avoidance system also has ports for interfacing Beidou satellite equipment.

Over 18 thousand of AIS vessel collision avoidance systems have been installed in Taizhou, Ningbo, Wenzhou in Zhejiang Province, Lianyungang in Jiangsu Province, and cities in Shandong Province. The AIS vessel collision avoidance system has received vast welcome and praise from both fishers and government officials of fishery administrative authorities. Our AIS vessel collision avoidance system has received Certificate for Type Approval of Marine Product from Register of the Fishing Vessel of the People's Republic of China.
