OGN-R PilotAware / Re: Data usage

I did that 70 hours ago and that's the figures I got. I'll try and record the totals each day for a few days.

but I do have the 360 Radar page active all the time

Can you disconnect and reset the router to see the new counts ?

Hi Lee,

Changed it as you suggested, still had a few issues today.  I've uploaded the three tracks and will PM you the links.  Something strange - it must be my setup but I cannot figure out why.

Todays aircraft was a PA28, the unit was sat flat on the panel, USB cable to the cigarette lighter USB socket.

I reset my Router about 70 hours ago and since then on that Ethernet line there has been 10.5 Gb uploaded and 17.3 Gb downloaded which is about 400 Mb per hour but I do have the 360 Radar page active all the time. The info page on port 8081 from the FLARM does give the traffic sent and received and it's about 15 Kb per hour.

We switched the receiver back on this morning and so far it has used just under 10 Mb per hour so it's very data hungry. More info to follow. I don't want to go back to just a flarm only receiver but unless we can find a cheaper solution than the one we have at the moment I will have to for this station.

Hi Peter
at 10MB/hour I work that out as 2.9KB/second
There are a number of interfaces using this internet data including :-
OGN (Flarm side, send only)
OGNR (PilotAware side, send/recv)
MLAT (recv only)

I have monitored the OGNR side (which includes MLAT - and it is pretty small)
I need to generate some concrete numbers for comparison

Its a difficult question - but what would be acceptable ?
I understand you are using a 4G connection, I think I saw unlimited data bundles for around £20/month ?

thx

Technical Support / Re: Use existing redundant ELT antenna for PA 1090mhz reception?

The only (slight) concern I would have with using the ELT antenna is, of course, that it is perfectly tuned to Airband frequencies. This means that possibly the SDR could get swamped and suffer a loss of sensitivity at times that you are transmitting on the aircraft's radio due to its proximity and strength of signal that won't be rejected by the ELT antenna.

This signal shouldn't be sufficient to damage the front end of the SDR but it might be worth repeating your tests whilst doing a long radio transmission on a permissable frequency to see if ADSB reception is degraded /corrupted in any way.

Hi again Pete,

Thanks for posting your results.

Yes that does seem to show a reduction in received signal strength, which shouldn’t of course have any serious effect on ‘Known Position’ targets - they should just appear on screen as normal. I would advise in the interests of safety running a longer Mode CS Range (i.e. Medium or even Long Range) until you can determine by flight testing how close Mode C or S Aircraft are getting before the visual warnings and audio alerts are triggered. CAT Mode-S (with it’s significantly higher power output) is usually a safe way to do some initial testing as it provides a reliable signal while following a predicted path and is easier to see at longer range, or try to fly a prearranged route with a colleague equipped with Mode-S (but not PAW/ADS-B). That will give you a better idea of what is a safe and practical Range setting for your setup.

Please let us know how you get on.

Best Regards

Peter

Stock PA ant(tuned), Apologies for the differing size screen shots, it was done in a hurry! and uploading seems to be a problem as above
43BF7A is a local ground station(ADSB?) and shows comparative signal strengths..i think
