AIS Application for ipad?
 
Before I purchase an ipad AIS application at random, I'm wondering if anyone has had any experience with any of the aps available? Please, before I buy, let's hear the good, the bad, and the ugly on this. Our ipad 1 has a gps receiver built in and we've been using INavx very successfully.

Any feedback is appreciated.

How would you be receiving AIS onto your iPad?

jackdale 20-03-2013 09:18

Re: AIS Application for ipad?
 
If you are using a web based AIS app, you need to know that they can have delays of up to an hour.

I have Marine Traffic on a Galaxy SIII. I have not a delay of that length.

Re: AIS Application for ipad?
 
iPads with 3G have a GPS receiver. The ones with WiFi only do not.

The best navigation app for the iPad is iNavX for $50.

https://itunes.apple.com/us/app/inav...286616280?mt=8

More navigation apps for the iPad...

With nav apps you pretty much get what you pay for.

I think "BOAT BEACON " is best.

Almost real time

Re: AIS Application for ipad?
 
AIS applications are not "real" AIS. They'll only work while you have internet connectivity, and you're relying on someone else's AIS reciever which is connected to the web. The position of that reciever(s) may not be best suited to your own location.

So basically, it may be fine close to shore, or in harbours, but out at sea it won't work.

Regain 20-03-2013 17:31

Thanks follow up Almost real time means not real time

I tested on the sea near vessels cross my boat The data shows almost real time May be minutes level delay

Not real time true AIS, BUT it is usefull for make sure vessel name who cross near by

If there was a cheap useful way of getting the AIS onto the iPad then its fine, but none of the AIS units have Bluetooth or WIFI bits in them.
It's got to happen soon. Someone has to bring it out... It should be cheap.

Re: AIS Application for ipad?
 
If your safety might depend on its accuracy, then I would get a real AIS and not a cellular connection based AIS website. If it's just a toy to keep you entertained then cellular based is no problem....and you don't even need an app for it. Just bring up marinetraffic.com.

Regain 20-03-2013 17:44

IPad Navigation is useful

But not to over depend on it


When you are costal, chart work using bearing compass is priority no1

iPad is just reference for navigation

It is Costal or Daysailing only , I think

But you need to pay only 1 or 2 USD for it

I think that's a load of crap, but on the subject of the thread, one needs propper AIS on propper ECN chart plotters.

Re: AIS Application for ipad?
 
Take a look at the easytrx 2 wifi, it is a wifi ais receiver that works with inavx. There is a receive only and a transponder version.

GPSNavX 20-03-2013 18:48

Re: AIS Application for ipad?
 
Another option is the Digital Yacht iAIS ..

iAIS

iNavX will also connect to the FREE SiiTech AIS server which has coverage in many areas.

dave777 20-03-2013 19:20

Re: AIS Application for ipad?
 
Another approach, perhaps more along the lines of the OP's question, is to have a PC on the boat forward via either BlueTooth or Wifi the AIS packets, by using the free open source OpenCPN. The AIS packets would come from an AIS unit feeding your PC, or your VHF if it does it. The delay would be imperceptable, not dependent upon the internet.

This would work for any handheld, tablet, phone, android etc. that can accept the packets as long as the phone gets wifi or bluetooth and the app supports it.

SailPenelope 20-03-2013 21:16

Re: AIS Application for ipad?
 
I don't know if the ipad app would be the same as iphone but I use ShipFinder Free. No cost. It's always worked well for me, but then I've had internet (I guess) when I needed it......shipping lanes near Los Angeles. I could identify the ships before I could see their hailing port and I was able to call them on the radio (was escorting a swimmer at the time......highly un-maneuverable). It worked. Price is right! Give it a try.

AIS information is transmitted over VHF. Unless your Ipad has inbuilt, or is connected to a VHF AIS receiver, it MUST be getting the AIS info through a cell tower.

Vesper Marine and Digital Yacht both have multiplexors that transmit wireless and have built in AIS receive (Digi Yacht) or send/receive(Vesper).

Not cheap but not that expensive either.

If there is a next boat it will almost certainly have one of the vesper boxes

XB-8000 - AIS Transponder with WiFi

Not affiliated merely find it interesting and thought it might be applicable.

Tomm0 21-03-2013 15:08

Now I have a class b transponder, so don't get me wrong, but what's with all the dissing of online AIS apps?

I used to use marine traffic, which I find is NOT delayed (maybe it depends where you live). I use it because it is in my pocket, one my wife's iPad, or wherever else I want it. When I'm trying to time a crossing of the shipping channel here in our bay, I can select a clear passage using marine traffic, roughly.

Better still, there was another app which calculated CPA, would give you configurable CPA alarms, and had other tricks: Boat Beacon. It also transmits your position (no, not to the ships... But to other online users). This was a much more functional app, and if you're not going to get a real one, this is the app I would recommend.

I used to leave the app running so people could see where I was using marine traffic online (makes the wife feel better to know where I am) and it was nice to look up the boat location when I'd left it at anchor somewhere too... Right where I left it.

Oh, and for the dinosaurs who still complain about electronic charts being worse than paper, wake up and smell the GPS signal. As someone who charted courses for submarines using paper charts, I can chart ... But I'd rather not, and I sure cant do it as fast and accurately as my plotter or my phone can.

44'cruisingcat 21-03-2013 22:26

Re: AIS Application for ipad?
 
It's not "dissing" of these apps. It simply the facts:

They will only work where you have mobile internet access.

They work via the internet, so there may or may not be delays. You won't know.

You are accessing AIS data via a receiver who's location you probably don't know, and which might not be appropriate for where you are. ie. a ship might be out of range of that reciever, but close to you.

Yes they will work in some places. They won't work everywhere.

+1 Great bit of kit.

Vesper uses wi Fi for the pad and the alogrithims sort out the CPA of interest.

I hope you're still,on the fence. AIS is important equipment. I use the iPad with WatchMate. Check a recent article at the oceantrader. co website. They had good information on using the iPad for this purpose. The URL iswww.oceantrader.co Good luck.

Re: AIS Application for ipad?
 
I ended up purchasing an AIS system from Garmin and integrating it into our vessel electronics. All of the Ipad aps require a constant internet signal which we don't have on board. AIS is transmitted via VHF radio, so basically.... it can't possibly work on an Ipad.

Actually AIS does work on iPad and iPhone. DigitalYacht makes an AIS receiver that receives the VHF signals and sends the AIS NMEA data wirelessly to the iPad or iPhone. Both Brookhouse and Shipmodul make NMEA multiplexers that will send NMEA data including that of AIS receivers and transponders wirelessly to iPad or iPhone.

Re: AIS Application for ipad?
 
You can view the AIS world wide it Live Ships Map - AIS - Vessel Traffic and Positions if there is a pick up transfer station in the area. There are many areas there is not AIS transmission, especially in desolate areas and up/down the coast. True AIS is boat/ship to boat/ship.

You can, and You have many choice

Garmin AIS has NMEA 183 out, just look in internet for NMEA to WiFi router
You can find good equipment from DigiTalYacht, or ShipModule, or cheap from vYacht Yacht automation. Last - cheap, but done by individual enthusiast personally on request, You can't find it in online shops.

correct connect and You can use many software on iPad/iPhone

Remarks - many of this device build it's own WiFi network on board, but if You request instruction from manufacturer - You can connect it to Your present onboard network - for example if You share 3G or WiFi extender internet onboard. In this case Your device - and work in internet and receive all NMEA information

manufacturer do this for easy installation process and to avoid user errors, but if You experience with networks, they send instruction, I have it for some of equipment, but not for all. Ask manufacturer before purchase.


About software:
1) MarineTrafic, mAIS and etc - exactly not online product, some time up to 2-3 hours delay. And - not work offshore
2) program like AIS radar - just for test Your equipment work correctly
3) best choice - iNavx or iSailor or some other chart software, when use it You can see real situation relation with chart

Personal opinion - don't buy Garmin WiFi :-)

Re: AIS Application for ipad?
 
I am surprised that no one has mentioned using old B&N/Amazon ereaders for stuff like this. I must be able to install "boat beacon" on it.

The digital ink screens use far less power than an ipad, are completely readable in direct sunlight, have touchscreens, they are dirt cheap used, battery lasts forever (new one has an 8 week battery life!), and you can put android on them.

The newer ones are backlit so you can read them at night.

Kinda sorta...

There's real VHF AIS... and then there's the possibility of viewing AIS transmitter locations on a cellular or Wi-Fi device... and those are sorta two diferrent things.

AIS signals transmitted or received with an AIS VHF transceiver can be repeated onto any number of devices via NMEA 200 (or 0183), Wi-Fi, Bluetooth, etc. and it can also be transmitted to an Internet "site" and then further relayed from there.

That's not really the same as an "app" on a cellular or Wi-Fi device... which essentially becomes a display device for viewing the original (real) AIS signal's location. The device can receive via Bluetooth, onboard or distant (within reason) Wi-Fi, Internet, etc.

Marinetraffic.com is just such an Internet repeater. My AIS transmits, a volunteer receiver up or down the Bay receives and repeats to Marinetraffic.com. I can use an onboard laptop or device to access Marinetraffic.com, and view my signal's location. (And of course other AIS receivers can view my location on their marine nav devices.)

But the Internet thing doesn't always work, certainly not enough for me to rely on. I'm transmitting right now, and as usual Marinetraffic.com has no clue about that (I just checked). My signal is slightly hidden from the two nearest volunteer receivers, because of my current location, so they can't repeat it to the website.

And if we had to depend on a Wi-Fi access point (i.e., not cellular), we wouldn't usually be able to view Internet stuff while underway, even with our onboard Wi-Fi range extender.

FWIW, we've compared Marinetraffic.com displays received via cellular devices to our own AIS data on the plotter display... and it's not too bad... sometimes. More often, the local receiver/repeaters apparently can't see all the nearby signals I can see on our plotter. (Six boats near us are transmitting right now, none visible on the website.) And it's worse when one of the nearby receiver/repeater stations is down (which seems to be common around here) -- in that situation, Marinetraffic.com becomes (at least temporarily) useless.

An onboard AIS transceiver solves all that for us. We've chosen to display the signal locations on the existing chartplotter. Given that we have an onboard chartplotter, we haven't found it necessary to leap through any hoops to also display AIS transmitter locations on tablets and smartphones.

Observations only.

Hi Chris,

Yes, I also describe real AIR receiver / transponder, but some time even if we connect it to chart plotter - we want see all on iPad or similar

My real cases:

1) MFD installed infront You just when You steer, but in 90% of case - I sit in cockpit and autopilot do my work :-) And in most case I use iPad connected for my on board network (when I mean WiFi - this is my WiFi permanently installed onboard and connected with all onboard equipment - SeaTalk, NMEA and etc)

2) my son on watch, I sleep in cabin - my Ipad show me all navigation information and/or sound signal to me about change situation like increase wind speed or etc

Regards, Vlad

David M 02-08-2013 09:46

Re: AIS Application for ipad?
 
As a professional mariner I would never use AIS information that comes from the internet. There is no telling how accurate or old this information is. It would be foolish to put the safety of the people I am responsible for on the information I get from an internet website.

Buy a real AIS receiver. In terms of what it costs to purchase and operate a boat and the safety benefits that they provide, they are relatively inexpensive.

Good examples of additional uses, Vlad.

FWIW, I see lots of traffic in your screenshot of the AIS display. We have far fewer boats/ships in our immediate vicinity that transmit AIS data... but then we also usually have 3x that much traffic nearby -- the majority by far doesn't transmit AIS.

Re: AIS Application for ipad?
 
I would also recommend iNAVx, it can be used with quite a lot of iPad based applications, for example wireless NMEA data, which is a great way to get your data onto the iPad as well. It also uses the GPS data, which saves using the iPads which kills the battery.

Re: AIS Application for ipad?
 
OK, so I'm an electronics dunderhead, but reading this and other how tos on You Tube and elsewhere, it strikes me that many of the solutions offered have built in redundancy, which I don't understand.

For example, the DMK Box appears to be a GPS with wifi, and there is a You Tube vid of how to connect this to a Standard Horizon 2120 (with AIS receiver built in) and connect to iPad with iNavX as chartplotter with AIS overlay.

So if the iPad was a 'wifi only' version, this sorta makes sense. But as most these days include built in GPS, doesn't this mean you have two GPS receivers?

Following this thought (my logic) if the iPad has GPS, why can't it be made to talk to the 2120 and give *its* GPS data to the VHF, therefore not needing the "redundant" GPS module in the DMK Box?

Clearly this would need to happen wirelessly, but surely then you would only need a 12vDC wireless router, like a cheap readily available domestic variety router....???

I'm guessing there is some VHF/wifi/GPS *logical* reason why this is not possible, but it looks like a cheaper solution than a stand alone AIS receiver, stand alone GPS, and/or 'mediator' like the DMK Box....let alone a GPS/wifi/AIS like the Vesper XB 8000.

Please respond in words of no more than two syllables, expand acronyms, and assume 5yr old IQ level human interface.... :) :)

Broken iPad = no GPS

twistedtree 29-11-2013 05:43

Re: AIS Application for ipad?
 
It's been said, but bears repeating. The internet AIS sources (marinetraffic, etc) are really unsuitable for any form of navigation. They are great for seeing what's going on around the world, tracking your friends, etc., but as a navigation tool they simply can't be relied on. Why?

1) They show traffic that is near a randomly located, land-based receiver, not what's near YOU. Real AIS (via VHF) shows what's near YOU, and that's what matters for navigation. That's because with real AIS, the receiver is on your boat, not in some house across town, or in another town somewhat near by.

2) There are significant gaps in coverage. That's because the receivers are located and operated by volunteers, so you have coverage where those enthusiast happen to be located. By way of example, I'm in a very busy commercial port on the east coast, and the only AIS targets that show on Marine Traffic are the biggest boats with very tall antennas. The AIS on my boat easily picks up 10x the number of targets. That's because there is no land-based receiver here. The closest ones are 10-15 miles in either direction. I've been thinking of becoming one of those volunteers and setting up a receiver station which would dramatically change that, but do you really want your "AIS navigation equipment" dependent on me following through on that?

4) The coverage gaps are not just city by city, but exist inside areas that appear to be well covered. I have had numerous occasions where I have been tied up in a port that appears to have great coverage on MarineTraffic, yet my boat and those around me don't show up. It's because there are blocked area where you are shadowed to the land-based receivers. When the receiver is on your boat, not in somebody's house across town or in the next town over, you are FAR FAR more likely to see what's around you.

4) People have mentioned delay, and some people have said there is none. Therein lies the problem. Sometimes there is an additional delay, and sometimes there isn't. You just don't know.

I love MarineTraffic, but it's really important to know what it is and what it isn't. It is not, in any way shape or form, a navigation tool. Using it to navigate is like using the local airport radar, or nearest weather radar to locate hazards near your boat.

Buzzman 29-11-2013 16:18

Re: AIS Application for ipad?
 
Did I mention 'MarineTraffic'...???

The question referred specifically to the SH 2120 which has a *VHF* AIS receiver built into the radio, but requires a GPS signal from an external source to 'merge' with the AIS data so that locally relevant 'real time' data is provided to the chartplotter (or the screen on the 2120 for that matter).

What is it with people that they insist on pushing their own wheelbarrow rather than either answering a question with a sensible rational response, or simply choosing not to provide any input at all......???

We *know* that a broken iPad means no GPS. Same as a broken Raymarine plotter or GPS antenna means "no GPS" on boats so equipped.....

This is stating the bleedingly obvious. Like, the sun rises in the morning. Or, it's raining, isn't it, or, what a lovely day....

If you have nothing *helpful* to say, please say nothing at all.....

Now, can someone with some *actual* knowledge provide a *helpful* response to my quite reasonable question...???

I'm certain, on the basis of simpe probability, that I am not the only one confused by all this hi-tech mumbo-jumbo..!!
