 |
|
I've got a customer who is developing some products
bound for airplanes . . . and like all inquisitive
designers, he would like to know what kinds of
gremlins might be lurking in his hardware BEFORE
he goes to the $150/hr EMC lab.
There's a line of software defined receivers or
(SDRs for short) capable of exceedingly broad
frequency coverage. These are teamed with software
that offers an equally broad range of receiving/
decoding capabilities.
If you, or perhaps any kids you know, are interested
in radio listening from 100Khz to 2.5 Ghz, check
out the products available off eBay and software
packages for low cost or even free. Here's
one of many videos on youtube that demonstrates
the capability of just one such paring
https://youtu.be/IaKEYEyrRgk
My primary interest right now is to help the fellow
get set up to 'sniff' emissions from his product.
But I suspect I'll learn more about the broader
possibilities for us . . . not the least of which
would be identifying and qualifying noises on
our airplanes.
More to follow . . . someday . . .
There's software that decodes ADSB and plots
the data onto a map.

Hi Bob
I'm not sure what you have written here, but the last sentence certainly rang a bell, and wondered if this is what you are talking about

So it is using appart from ADSB and XPDR a proprietary protocol named
P3I for apparently some radio GPS transmission between planes.
Its a pity why he is not using a well defined standard since years
(Flarm); but might be license costs. So we just introduce yet another
traffic detection mode.

Sore point: 'FLARM' is not available to non-Flarm registered users

The only connection I've made with respect to
ADSB intercepts is what was demonstrated on
the linked video.
Most certainly, this capability is deeply dependent
on some detailed knowledge of ADSB along with the
talents to write software. No doubt, there are
software packages with amazing capability . . .
for a price.
At the same time, there exists a boatload of open
source packages that are free.
For the moment, my interest is focused on using
the SDR as a noise-source identification and
qualification tool. I'll leave it up to you guys
to explore broader interests to our brothers
on the List . . .

For anybody interested in the PilotAware application and hardware, and it is very noteworthy in that it not only receives and displays ADSB traffic on your navigation application but also generates its own signal for display if your aircraft is not ADSB equipped, the local radio transceiver used is only good for Europe. It uses a frequency of 868 MHz, or thereabouts from memory, which is not available in the US, Canada, Australia or much of the rest of the world. Hopefully the team will develop a hardware version which can be used at say 921 MHz so that we can all benefit from it.

Instead of waiting on an incompatible European ADS-B box. Check out this one: https://www.openflightsolutions.com/flightbox/
Have a friend who just installed one in his C182 and is really pleased with how well it works.

No need to wait if ADS-B is all you want, Joe. PilotAware does that just fine now. You don't need its European transceiver to receive and display ADS-B. What the additional radio transceiver does is generate a signal containing the required positional information for an aircraft that is not ADS-B equipped. When received by another PAW equipped aircraft, PAW then displays that aircraft along with any ADS-B targets received. It is therefore really an advance on the flightbox offering, at least in Europe.
It uses a licence free ISM frequency allocation to transmit and receive the non-ADS-B data and therein lies the difficulty for use outside Europe. The ISM allocation used in Europe is smack in the middle of a GSM band, and heavily used, here in Australia, for example.

Bob,
Checkout rfexplorer.com. They have a neat setup for RF analysis using the RF Explorer.
If I wasn't building a spectrum analyzer then this would be my next purchase.

Yes, I've seen those. There are numerous hardware configurations
on eBay . . . and a variety of open source software support programs
as well. These are simply a more 'self contained' version of the
SDR modules. They certainly have an advantage of offering hand-held
utility.
I will probably have one of broad-band versions at some time
in the future.
