The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision ...

2020年4月6日 · AIS, radar target enhancers and radar each give an added layer of observation to the ‘Mk1 eyeball’. While radar was once the only real option for blind navigation and collision avoidance, there is now a range of technology to help yachts wanting to see and be seen, but each of the options has its own strengths and limitations.

AIS (Automatic Identification System) is the mariner's most significant development in navigation safety since the introduction of radar. This is a digital positional awareness system operating in the Very High Frequency (VHF) maritime band.

2024年8月28日 · Here’s a look at the pros and cons of AIS or radar and some thoughts on which one might be right for your boat. What Is AIS? AIS stands for Automatic Identification System. It’s a special VHF radio on a boat that sends a digital signal to nearby boats with receivers.

雷达和自动识别系统（Automatic Identification System，AIS）是当下船上配备最多的导航设备，而且二者的信息具有一定的互补性和冗余性 [1]，将雷达和AIS的信息进行融合，有利于改善船舶对周围障碍物的探测性能、提高船舶导航信息的精度和可靠性，是未来船舶导航技术发展的重要方向。 雷达是主动式传感器，发送信号、接收和处理返送回来的信号，不能接收其他雷达的信号 [2]。 雷达可以对运动和静止的目标进行跟踪勘测，提供距离、方位、航速、航向等信息，并 …
