Plots markers from received AIS radio signals

Its still a very basic/alpha stage, to get this working you need the following:

• an SDR device (https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/)
• Make sure to download the sdr-rtl library (https://packages.debian.org/bullseye/rtl-sdr)
• Download & Compile : https://github.com/dgiardini/rtl-ais
• Setup/import sql table from the ais.sql file with your db software (i used MariaDB)
• Run rtl_ais -h 127.0.0.1 -P 10110
• Run php -f parser.php

The AIS receiver program will attempt to load the RTL library and sets up the SDR device, spits out data to the UDP defined address and port, then our php script will capture these messages so we create a nice barrier between our device and front-end.

Now you want to run the rtl-ais in a nohup <app> & so it will run even if you log out. Make sure if you want to stop this, to do it properly with kill -3 <pid> and not aggressivly with kill -9 <pid> because you could create a faulty USB device status (unclosed device).

Green markers are recent received signals, the purple markers are stale positions that have not seen any recent update. This can be due to bad/blocked reception or simply out of reach.
