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.

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.

Two vital tools in a seafarer's arsenal are AIS (Automatic Identification System) and RADAR (Radio Detection and Ranging). While both play key roles in maritime safety, they serve distinct purposes. Let's delve into the differences between AIS and RADAR to better understand their unique functionalities.

The AIS broadcast provides the position and purpose of an aid, such as a port or starboard lateral buoy, even before it is close enough to be visible from a ship or to provide a radar return. This can help mariners confirm their ship's position or to prepare to …

Diverging from AIS’s reliance on transponder signals, radar emits electromagnetic pulses and gauges their reflections to construct a visual depiction of the surroundings. Offering broader coverage and extended detection ranges compared to AIS, radar excels in long-range surveillance and early threat detection.

Both radar and AIS can be invaluable in accessing a potential collision threat and we absolutely recommend using the two together. We often overlay both radar and AIS on our chart plotter and it’s always interesting to see what each picks up.

2025年1月24日 · While radar and AIS each have their strengths, combining the two systems provides unparalleled situational awareness. Radar can detect all physical targets, while AIS identifies and provides detailed information about other equipped vessels.

2013年6月28日 · There is much more to both of these systems than just collision avoidance, of course – radar can be used to resolve coastlines and spot squalls, while AIS allows you to track and hail shipping. For the cruising sailor, though, with a finite budget, both technologies have elements to recommend them.

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 ...
