FR24 receiver - also AIS support?

[dunno]

hi,

before I got addicted to FR24 I used to spend quite some time on the marinetraffic website [1].

both services "suffer" from uncovered areas, and my impression is that in many cases these areas cover the same regions.

therefore the idea to add AIS receiving/reporting functionality to the FR24 receiver. of course no use for this in the center of continents, but coastal regions would benefit significantly (i.e. west/east coast of africa). also, for the user it is more convenient to install/maintain just one receiver than two.

of course, only users at the coast or close to big rivers would get one; others just the ADS version.

still, there are many issues to sort out (technology, cost sharing with the MT guys etc.)

just my 2cents.

Hi,
You should also forward your info to the ModesBEAST company. The maker of the custom FR24 box.
Maybe they will release a network box version for AIS.

FR24 needs to focus, so we will not produce an AIS receiver. But there is still a lot of things that can be improved with ModeS/ADS-B hardware, so me and Günter made some tests of new hardware earlier today. It was very cold but the results are good

Mike,

That's what I'd call dedication. Coming from an electrical background though leaves me wondering. How does the cold (and by the looks of it, very cold) affect those electronic components and your results? How would the results vary say from there to here in Australia out west in 45-50*c+ heat (in the shade)? I do notice a seasonal variation in my basestation unit as well as with humidity/atmospherics conditions just as I do with my scanner. They dont like those solar flares at all.

Great work by the way and thanks to all you guys.

Regards,
Gregg

Günter makes good things so some weather should not be a problem. We had to climb the highest peak in Stockholm just to make a simple "proof or concept" and not a complicated scientific test.

+45 is just an amazing contrast to our -5 and snow fall for 96 hours.

Mike, could you talk a little bit about the hardware?? Looks interesting. I would love to help somehow. The antenna you're using for the tests is this one?? http://f5ann.pagesperso-orange.fr/An...MHz/index.html

Thanks

Neat idea, but AIS uses VHF frequencies, where ADS-B is using 1090MHz. Big difference and would likely require 2 separate receivers and 2 separate antennas.

I'd love to put an AIS receiver at my site. I contacted a few of the websites, but no luck. My site is almost 1000 feet above the Monterey Bay, and I have a great view of a big piece of the Pacific Ocean. If I could find a relatively inexpensive AIS receiver, I'd put one up myself.

Mike,

want to swap places? You may need a few good sized heatsinks on those units over here.

I haven't seen dedicated receivers, but what you can do is use any VHF receiver that has the range of AIS frequencies and an output called discriminator tap that goes to your PC soundcard. (It's a signal that is unfiltered, because normally the signal would be filtered to only include the audio and then amplified for the speaker) There is a lot of software to decode it like GNU AIS.

Hope that helps, but AIS is a different thing to talk about. Here is airliners information.

Congratulations !

You guys put your life, souls and blood into keeping this hobby going.

Sorry, I cannot say anything about the receiver hardware yet. The antenna is for sure relative to the one you link to, but I think Gunther mentioned that there might be some small differences.

check out http://www.marinetraffic.com/ais/add...spx?level1=150
you'll also find a list of AIS receivers there. I was about to acquire the NASA AIS receiver, but my area is already covered - as seems to be case with your area.

let's leave it at this since we are a bit off topic here.

tnx guys for your answers.

I just looked at Monterrey Bay, there is a receiver there now, but it's only 8m above sea level. Quite a good reception, though. http://www.marinetraffic.com/ais/def...48&oldmmsi=230

Did you try the "Cover your area" tab at the top of the page? If you qualify (good luck!) they will send you a receiver. If not, there is one for 99pound/$179 US, USB compatible , all you need is the VHF antenna. This is the main link, just follow it down to US option http://www.radargadgets.com/

Hi !
I did not find option to send PM and would like to add my 21 cents here. I am both AIS and ADS-B user so those who would like to join and share AIS there are quite a few web pages about AIS.There is software ,most popular so far which can be found at
http://www.coaa.co.uk/shipplotter.htm and group about it at http://groups.yahoo.com/group/shipplotter/ .Another option is using VHF scanner and sound card.All about it please find at http://groups.yahoo.com/group/aismon/
There are some companies which could offer you AIS equipment for free in exchange for 24/7 feed from your location.Some already mentioned Marine Traffic which is most popular and with biggest coverage so far but some may contact Fleetmon as well.Very nice mapping software and database.You can apply if your area has not been covered or you got better spot.Maybe higher ground etc.
This is where you can get info at http://www.fleetmon.com/products/ais_partner
Wish you luck and sorry for AIS info on this AIR forum.
Please find screenshot of San Francisco area enclosed.
