Airnav Radarbox newb q's

Post by S109 » 28 Aug 2013, 19:59

Hi,

I keep looking at these but to be honest I don't really know a lot about them :oops: What exactly will it do ? What's the difference between me spending a few hundred £'s on one compared to a few quid on something like Flightradar24 app.

And could I hook the box up to my X-50 ?

Thanks.

Similar to the flightradar page, it will display live aircraft positions on a map.

If you dont want to spend hundreds of £ on a Airnav box you could try one of these - https://www.cosycave.co.uk/product.php?id_product=285

Its a freeview usb stick but by replacing the driver it can be used as an ADS-B reciever and even as a scanner. I have one and it is great. Just download some software to display the aircraft on a map (Planeplotter, GlobeS, Virtual Radar Server etc) Why spend hundreds of £.

The ADS-B transmitters on aircraft are at least 75watts and sometimes there will be nothing but air between the aircraft and your antenna so you are guaranteed to pick up some broadcasts.

An antenna tuned for 1090MHz is likely to work noticeably better.

click for a blog entry by someone who reports 40Km range with a cheap 'wideband' scanner antenna and 100Km with a 1090MHz quarter wave whip.

Having the antenna above obstructions makes a big difference. An acquaintance of mine used an antenna on a first floor window sill and the range was much further in the direction looking out of the window.

Your 15 meters of westflex should have acceptable loss.
A mast head preamp made to only amplify 1090MHz might or might not give a noticeably better reception with a digital TV stick.

Thanks both :)

So what else is out there apart from Airnav. I know there's the Kinetic and the ones mentioned above. Is planeplotter just a free software ? I would still need some type of dongle & antenna ?

Is there anyway of linking the my radio/scanner so you can hear as well as see them ?

Thanks. :oops:

I believe you can receive ACARS with any scanner that covers VHF airband (ie almost any scanner). You just need a cable (usually 3.5mm jack to jack) to connect the audio out on the scanner to the line in on your computer and some free software from the internet.
That is mainly messages to air traffic control and airline messages (yawn), it's not aircraft positions.

As to your actual question; from http://www.discriminator.nl/faq/index-en.html
Can I use the discriminator output for ADS-B?

ADS-B (Mode S with extended squitter) is transmitted on 1090 MHz. Most scanners can't receive this frequency. Apart from that, the bandwith of an ADS-B signal is about 2 MHz. A scanner has a receiver bandwith of about 25 kHz, and is not suited to receive these broadband signals.

I am using the Micro-Adsb dongle .... http://www.microadsb.com/

It`s a tv dongle sized unit but it works well for me and is very easy to set up. I use it with PlanePlotter.
The more expensive units would probably have a better range and if I was going for one of those I would go for the SBS3. To be honest I would not choose Airnavs offerings at all.
A couple of links to Adsb specific forums are below.
