Put an AIS antenna on the roof #1481

Open amcewen opened 3 years ago

amcewen commented 3 years ago

While there is scaffolding up for the roof work, John C is planning to install a LoRaWAN gateway on the roof (and has permission from the landlord).

I'm wondering if we should put an AIS antenna up there too, so we could set up a Raspberry Pi to decode the ship traffic on the Mersey

Yes, and Flight Radar/ADSB Exchange too. I haven’t investigated AIS myself but the planes are really easy, both Flight Radar and ADSB Exchange give easy scripts (and even a Pi image). TBH I don’t know if that would require a second SDR and antenna or if AIS and ADS can run over the same hardware.

AIS is 162MHz. I've not looked at the plane stuff at all. We can probably ask @kayharvey for advice on any antenna issues if you find out the frequencies it uses

johnmckerrell commented 3 years ago

Ah, ADSB is 1090MHz so I guess not. Might be worth running some tests to see if we'd actually be able to receive the traffic from the river where we are, could still be plenty of buildings blocking the path?

amcewen commented 3 years ago

Have ordered an antenna and an SDR module to try it out. Probably not all going to get here before the scaffolding comes down though :-/

amcewen commented 3 years ago

The antenna and module have turned up now. Handily @kayharvey had a suitable cable because the pigtails I bought didn't have quite the right connectors. Now to get it up and running...
