What is ATIS

[MarkV]

I saw this as a feature of a VHF and wondered what it is. The blurb said it was somthing required by european inland waterways.

That's right. It means that , for instance Kustwacht Post Ouddorp (Coast Guard) can identify a ship appearing on their screen;or calling them over VHF: they instantly know its call sign, and who they're dealing with.
It has to be programmed into your set though.

I'm too lazy to look it up, but I think it stand for Auromatic Transmission Identification Signal (or something like that).

Is this the same thing as I recently saw during a review of radar/plotters recently in PBO? Is it likly to be just a transmitter or could such a thing receive other ships info and interface to a plotter. The radio was quite cheep (about £150) so I guess it is quite basic.

Is that the reason that Dutch VHF calls end with a squawk like a parrot?

ATIS - Automatic Transmitter Identification Signal, is simply a protocol built into some vhf radios, and sends out a signal at the end of transmission (and roughly every 5 minutes over prolonged transmission) giving a unique identifier to that radio (similar to a call sign). That's the only information it provides.

AIS - Automatic Identification System, is a different system. A dedicated transmitter on board sends out continual information of speed, heading, status, ship name etc etc, and this is what can be received on AIS sets, and interfaced to suitably equipped plotters and radars. You can see it working live here:

have a look at the shipping in the English Channel or Southampton Water for example

aislive is, as you say, well worth a look. I, for one, appreciated your drawing attention to it in a previous post Brendan.

Unfortunately it seems to me that one now has to subscribe (at great cost) to get anything other than the ships name. Have you found the same?

Still interesting though.

Just tried registering again, and they say free of charge.

Here's an example:

Though seem to have lost some resolution somewhere, it's a lot clearer on the site

Yes the registering on the aislive site is free. But whatever was happening has stopped here and am now get the ships information again - strange. Must have been paw trouble.

'Cause I stopped getting the data a short while back I assumed that it was due to the little note at the bottom of the screen about the ships registration info not being available without registration on the other site they mention (a Fairplay/Lloyds Register one) which is not free (very unfree in fact).

Anyway all's now well and my last post can be regarded as being from a cross eyed cat /forums/images/icons/smile.gif.

Was of interest having another look this morning, spurred by your post, as the ship that did our Bermuda boat delivery is now ploughing up the English Channel I see - has done NZ, Tasmania (for our pickup), Panama Canal, Bermuda, Canada, and now English Channel - as far as I am aware the crew have not been ashore in that time. As an example, in Bermuda they had to anchor off to do the lifts and were only there for about 6 hours and on their way again - after the new boats were clear I MoBo'd to the ship to witness the delivery handover and they pulled the ladder and anchor within minutes of us doing so. Life on the waves is not as it used to be /forums/images/icons/frown.gif.

Hello Mark I am sure the other posters are correct however with all acronyms there is room for ambiguity. ATIS also stands for Airport Terminal Information Service and is that continuous broadcast of temperature QNH (baro pressure sea level) wind speed and direction and any other warnings from an airport. It can be broadcast on LF beacons 200 to 400khz, VOR beacons 108 to 118 Mhz or on a dedicated VHF (AM) channel 118 to 136Mhz so just be aware there is a remote possibility this is what they are talking about. NB all the above are AM modulation where your ship VHF is FM modulation so usually incompatble unless the manufacturers have gone to some trouble

Given the debate in other threads about illegal use of VHF (unlicensed sets and operators) and abuse of the system wouldn't the adoption of this system help here in the UK. I know it would require a system where sets were registered at point of sale but that might be better than a slow descent into chaos. It would make it possible to identify anyone broadcasting which can't be done at the moment.

I'm suprised that the whole lot wasn't swept up with DSC, it would make a lot of sence (to my simple way of thinking).

Actually, Automatic Terminal Information System, not Airport, and why the heck would this system be used on European Inland Waterways, as specified in the original post?????? If the planes were flying that low they'd be more concerned with black boxes and not ATIS.

Not a great deal of ambiguity there, given the specific mention of inland waterways, unless people are really determined to find out how many different acronyms there are for ATIS using google:

Apprenticeship Training Information System - nope not related to inland waterways
Afval Technologie Informatie Systeem - nope not related to inland waterways
Associazione Tecnici e Installatori della Sardegna - nope not related to inland waterways
Air Travel Information Service - nope not related to inland waterways
Advanced Traveler Information Systems - nope not related to inland waterways
Air Tourisme Instruction Services - nope not related to inland waterways
even the Alliance for Telecommunications Industry Solutions , at ATIS.org - nope, definitely not related to inland waterways.
and about a few hundred others, all not related to inland waterways.

Please read the question before diving in with a confusing and irrelevant answer!

As related to VHF, ATIS stands for 'Automatic Transmitter Identification System' (as said before) and is mandentory for 'Rijn' lands (Schweitz, Germany, Luxembourg, Belgium and Holland) since 1996. With a licence, you will become an unique ATIS-number, which should be programmed in a new VHF or reprogrammed in case of 2nd hand models (additional modules are available for 'old' sets). Good thing is, this is an unique indentification code which will be send automatically after the release of the PTT button (or after eacht x mins talking). This means that without voice, a coastguard station can indentify a ship, once it starts transmitting. Also silly radiochecks on channel 16 will be rewarded with a nice letter delivered at your home address...... Modern VHF set also includes an ATIS killer module, which doesn't kill the indentification code, but the funny acoustic parots' squeek after the transmission. ATIS is a personal code which only end once the license (anual) is not renewed....
