AIS

mossi i broker, nemam ni pribliznu ideju koliko AIS receive lokacija ima u rumuniji , a jos manje koliko njih je povezano na internet .... tako da se moze desiti da samo iskrsnu ladje na nekom delu ....

ais radi i bez interneta tako sto brodovi "vide" jedan drugog putem VHF-a koji prenosi 26 vrsta podataka (od pozicije , brzine , pa do imena broda vrste tereta i slicno...)

otvori sam novu temu pa ako neko bas hoce da vidi polozaj svih brodova na svetu sa AIS-om  ima plugin i neka ga skine .. radi ko sat a vuce ko Big Ben...

Kap,
hvala na strpljenju, opet bi opleo bez razloga....

Primarni medij za razmenu AIS informacija je još uvek VHF. Internet je "poštapalica" za razmenu informacija između AIS baznih stanica koje se ne "čuju" kroz VHF etar. Prikaz AIS meta preko interneta je dalji razvoj te teme...

Dakle, da bi se na nekom od navedenih sajtova pojavile AIS mete sa Dunava, potrebno je da neko prikači svoj AIS prijemnik na računar i na internet:


--- Citat ---What equipment and software do I need?

A typical base AIS station is shown on the picture above. Obtain and connect to your PC an AIS receiver with an external VHF antenna and send the collected data through your Internet connection. In detail:

1. You need an AIS receiver.
You may buy one from a local marine electronics shop or you may order one from an online shop. In case you are located in an area of special interest (high traffic port or area, canal, high altitude, etc.) which is not alreday covered, we will try to provide an AIS Receiver for free.
We have tested the following devices with our software, with similar results:

•COMAR SLR200 dual channel (~500 €) www.parissinos.gr
•EasyAIS – dual channel (~300 €) www.easyais.com
•SaNav AIS-2 – dual channel (~350 €) www.navtronics.gr, www.sanav.com
•Smart Radio SR162 – dual channel (~400 €) or SR161 – single channel (~180 €) smartradio.diytrade.com
If you are not sure whether your location is suitable for AIS data reception and thus you do not want to buy a device, we can lend you an AIS receiver unit, to try it. You will have to return it to us within one month.

Dakle stvar je što kod nas niko nema AIS prijemnik koji bi prikačio na internet i poslao podatke na server poput ovoga.... Kao što već rekoh, nadam se da ću do sajma poterati onaj prijemnik koji mi je na "testu" već godinu dana da radi, pa da se na sajmu igramo position trackinga sa Garmin VHF-om i praćenja AIS meta sa NASA Marine AIS prijemnikom...

Pera GARMIN:
A može i alternativno, preko zvučne kartice PC-a i VHF prijemnika:

--- Citat ---I already have a wideband or a VHF receiver. Can I use it to collect AIS data?
If you already have a wideband receiver or a marine VHF radiotelephone, it is possible to use it to collect AIS data and send them to the central server, without buying a specialized AIS receiver. You have to follow the steps below:

•Tune your receiver at one of the frequencies 161,975 MHz or 162,025 MHz (with FM modulation) or if you operate a VHF radiotelephone, tune it at one of the channels 87 or 88. If there is AIS signal reception, you will hear a ‘noise’ repeated at very short periods.
•Connect the discriminator output of your receiver to the input (line-in or microphone) of your computer (for more information on discriminator output of receivers see http://www.discriminator.nl).
•Install the software AIS_Monitor in your computer from here: AISMon_2.2.0.exe (Thanks to Dave Houy: http://groups.yahoo.com/group/aismon/)
•Run the AISmon program, select the sound card of your PC and configure the UDP data output to 195.251.168.18:5351. See the ships you are receiving immediately on the real-time map!

da li ce bazne stanice imati povezanost sa internetom ?

btw sta se desava kada dva broda u isto vreme posalju signal , vhf bas ne voli preklapanja?
