Cheapest AIS

Welcome to the world of AIS. ais on the cheap

The advanced collision avoidance system.ais on the cheap

AIS is the acronym for “Automatic Identification System”.
A VHF radio based system used by commercial shipping since 2004.
AIS detects virtually any commercial shipping within a 400+ square Mile area surrounding your position and warns you of their presence.
The software we supply, sounds an alarm well in advance of when a collision is probable,
AIS also shows on screen the point of impact, the ships current GPS position, speed and course.
Knowing this information gives you plenty time to take action and avoid a collision.
AIS data are updated Automatically every few seconds
Every yacht can have access to this information.

"Stand-alone AIS transponder/receiver systems" are rather expensive.
This website will show you a much cheaper way to receive and plot AIS data on screen.

AIS data are transmitted on 2 VHF frequencies.
Seeing you already have a VHF radio on your yacht, there is no point in duplication by buying a dedicated ais receiver.

To visualize the data, all you need is an additional rc-circuit added to your VHF radio and some decoding software for your laptop.
Then connect the VHF to your laptop for tracking and navigating in real time.

Need more background? Please keep reading......... OR check if your VHF is suitable, for receiving AIS data .

(The chart is updated every 2 minutes or so, with data supplied by www.marinetraffic.com)
A.I.S. is a display system that shows every commercial ship within your VHF-radio range on an LCD screen.
These data can be overlaid on electronic charts for your area.
Each ship that registers on screen indicates its: GPS Position, speed, Course, name, destination, call-sign, cargo, MMSI registration, its size and more.
Vector lines show their track for approx. the last 30 minutes.
AIS is different than radar and shows information without clutter on screen.
The LCD display shows security information, like: The closest point of approach, time to closest point of approach and other navigation information.
It works irrespective, whether rain or shine... UNLIKE RADAR

AIS information was previously only available to Vessel Traffic Management Centers
It is now available for every yacht/ship.
When installed, you will have the ability to contact any ship on VHF by name, rather than by "Klingons off my Starboard Bow" or something similar.
The commercial version is a shipboard broadcast system that consists of a transponder, operating in the VHF marine band on the high side of duplex channels 87B and 88B.
The cost of these transponders is rather high and out of reach of most yachtsmen BUT you can receive the information they transmit, virtually for free.

If you have a laptop, a GPS and a VHF radio. Than you already have 99.9% of the hardware for AIS reception.......
