目前,在船舶监管领域,AIS系统和GPS公网监控系统作为VTS系统中的辅助系统,相互共存并发挥着重大作用。与VTS系统相比,它们能够准确确定监管船舶的各种动态信息和静态信息,而不需要人为进行呼叫就能够自动识别。其中AIS系统中,classA主要应用于IMO公约规定的大于300总吨以上的船舶,AIS classB和GPS公网监控系统则应用于小型内河或沿海船舶。 Currently, in the field of ship supervision, AIS systems and GPS public network monitoring systems co-exist and play an important role as auxiliary systems in VTS systems. Compared with the VTS system, they can accurately determine a variety of dynamic information and static information of the supervision of the ship, without the need for people to automatically identify the call. Among the AIS systems, class A is mainly applied to ships of more than 300 GT as stipulated in the IMO Convention. AIS classB and GPS public network monitoring systems are applied to small inland waterways or coastal vessels.
