ADS-B reciever

[hpeer]

Someone jut sent me this link for a $150 ADS-B reciever. Interesting for the weather alone.

Any thoughts about this for marine use?

Does it receive weather transmissions, or just GPS coordinates?

I see a different model that seems to receive weather, but it's triple the price.

All that is assuming you're looking at the skypro receiver that retails for $150. You need FIS-B for weather.

Duuhh....adding link....

No idea what ADS-B is. How does it help us sailors?

[hpeer]

Not sure. What caught my eye was the WAAS for GPS on tablets. But after reading more closely I'm confused. Says you need to be able 500', but that should effect weather reports, not enhanced GPS.

I was hoping someone here could help.

You can receive ads-b an awful lot cheaper...

Not that it's much use on a boat

AS I understand it ADS-B is the aviation equivalent of AIS using UHF.

ADS-B ground stations can also transmit weather information - so if you are within line of sight of an ADS-B station (usually an airport) it may serve to give local weather conditions at that location.

Don't see it being any use on a boat.

We have ADS in our airplanes at work. Basically, they are fancy transponders which provide Air Traffic Controllers with updated position information. This works really well in non-radar environments like when flying over an ocean or the North Pole. They typically use the Inmarsat Satellite system. You can also use them for communication when HF frequencies are acting up due to solar flares or other conditions.

Don't see the point for a boat when something like a DeLorme InReach will basically suffice. You can even get met reports for your position from Spot Weather. Wind, wave and pressure forecasts sent directly to your device for just a few bucks a month.

I didn't realise that ADS_B could communicate with satellites.

According to these maps, it only works within LOS of ground stations:

Australia: ADS-B coverage | Airservices

US: ADS-B Altitude Coverage

There is ADS B and ADS C. Most commercial aircraft have upgraded to ADS C. For us, in the cockpit it is seamless. It can use VHF, HF and Sat. Domestically, it is likely using a ground station. (B) On the ocean or over the pole however, it would be using HF or Sat. The ADS simply sends out position reports and it can also be interrogated by the control agency. The communication side of things is called CPDLC, ( Controller Pilot Data Link Communications. ) it will also use HF or Sat if needed. With CPDLC, we communicate with ATC via text messaging rather than voice.

I love the map used by the US. So typical, everything stops at the 49th.

Just as you said, an AIS unit on a boat basically does the same thing as ADS but it's range is limited by line of sight from the VHF antennae location. However, combine an AIS with a satellite based texting unit like the DeLorme InReach SE and for less than a 1000 bucks, you basically have the same suite we have in a 100 million dollar airplane!
