Title: Radarbox delayed data after powered for a long time
Post by: homestea on December 29, 2009, 05:07:20 PM
I have noticed that if i keep my Radarbox powered and on for and extended period (about 12 or more hours) it seems the live ADS-B traffic being recieved by the unit gets delayed by at least 10-20 seconds.  To remedy this I just unplug the radarbox usb and plug it in again and I see that the delay goes away and the positions are again live.  Has anybody else noticed this effect?  I notice this effect because i like to leave the radarbox on 24-7 to share my data with other users.

No, I've never had this problem.  How do you know that there is a 10-20 second delay?  Are you comparing this with aircraft you can see?

We have never seen this issue either, we have dozens of machines runing 24/7, some at airports and used by certain company who need accurate data and its never been mentioned to us by them either.

Hi there, im still quite new to this got my box for christmas.
Now at the bottom left of the airnav screen near the hardware connected box i have a message that counts down for 30 seconds is this the same thing as mentioned above?

Yes, I'm comparing the display to what i am seeing out my window.  I can then unplug the USB and reconnect it and instantly I see a jump in the program to the correct aircraft position. I am running windows 7, so i wonder it there may be a bug of some kind where a buffer is filling then begins to delay.

Have you changed the default setting for the refresh, ie higher than 1000ms? the higher the number the longer the refresh delay.
Title: Re: Radarbox delayed data after powered for a long time
Post by: eggplant on December 29, 2009, 09:10:41 PM
Hmm.  I am using Windows 7 and my ANRB is normally on 24/7. I haven't noticed any delay. I have some landmarks which I can view from my window to gauge the correct position of aircraft - I'll keep a close eye next time we get a clear day, so could be six months or so....and report further then.

For some reason, mine was set to 4000ms!! I dont know how that happened! I changed it back to 1000.  I will let you know if that was causing the problem! Thanks for the feedback!

Hi! Been there a few times to leave the RB on and when I get home, I see that in MyLog was a cut in the receipt list.

When happen again put here a screenshot.

Post by: homestea on December 31, 2009, 05:02:23 AM
after changing the refresh to 1000, I am still experiencing a build up of delay over just a couple hours.  This delay translates to about a 10-15 second delay of actual aircraft position and what is being displayed on the map.  I dont know what i can do to resolve this short of uninstalling the program and drivers and reinstalling everything from scratch.  Is there some kind of usb data speed setting, perhaps my usb port is operating at a slower baud rate of what the radarbox is sending it out, and thus putting excess data into a buffer, causing the delay?! I'm very puzzled why it is acting ths way and nobody else seems to have this problem.

I also notice that when I listen to the control tower departure, and the departing aircraft says the altitude it is climing through, it is often off by 500ft or more from what the softwaare says.  This applies to mode-s aircraft as well as ads-b aircraft.

When an aircraft is climbing out, the controller is required to verify the Mode C (the level readout) displayed on the screen compared to the level the pilot says he is passing.  The tolerance for this is 300ft - what you see on the screen must be within 300ft of what the pilot says.  To get within 500ft using a non-calibrated but of kit that costs less than GBP400 is pretty good!

In level flight the tolerance is 200ft.

See the link below for more details regarding verification of Mode C and requirements for assuming an aircraft is level:

http://www.ecacnav.com/content.asp?PageID=395

(it's been a while since I've put this into practice, so I'll sure that somebody more current will correct me here if I've got this wrong!)

Not sure what amount of calibration of a RB/SBS would produce or eliminate any difference between the altitude the aircraft is transmitting and what the box is decoding, but point taken.

It's also worth bearing in mind that a departing aircraft could easily be climbing out at 3000fpm, so in the 5 seconds or so that a pilot takes to report his callsign and altitude he's already 250' higher than he says he is  :-)

Time taken to process the data would be critical here.  This would be a specified requirement for ATC use, but is largely irrelevant with a 'hobby' item.

The Hi-Brite display in the ATC Visual Control Room (VCR) is a slave using the same data shown downstairs in Approach, but you are not allowed to control on it, as it isn't calibrated for this use.  You can use it to gain situational awareness and to identify zone crossers, but you can't actually 'control' with it.

Hi

Over the past few days, I've had my box on continually, and have experienced several dodgy positional hits on my box for traffic leaving EGCC (Manchester) when observing it from my house - basically the position on the map is lagging behind where the actual aircraft is in real time (not currently using the network either so it's not that!) - it's not massively out but it is noticeable in that traffic is actually visable to the east of my house , when on the box it's west of my home location,(which hasn't been changed for approx 18 months).

As I type this, everything is spot on as a BMI Baby 737 has just departed EGCC and is bang on positionally

Could it be due to the less than settled weather we've been having recently?

Happy New Year to all!

Rich

I'll see if i can post a video of the positional data error accumulation that i am getting.  I wonder if my radarbox hardware could be faulty?
Title: Re: Radarbox delayed data after powered for a long time
Post by: homestea on December 31, 2009, 02:58:49 PM
Hey Marpleman, try unplugging the USB cord then reconnecting it and see if you see a "jump" in position (to a more accurate positioning) like i am getting. You seem like you are experiencing exactly what i am, though it seems ALL of my traffic is lagging.
Title: Re: Radarbox delayed data after powered for a long time
Post by: Marpleman on January 01, 2010, 10:05:35 AM
Hi homestea

I'm only observing this with certain positional data, not all coverage. Doing what you suggested doesn't really make it any clearer to discern what's happening.

Had a strange one yeasterday when a LH A330 "stood still" and was overtaken on the screen by a KLM B777 which were both visibly identified passing several miles due north heading US bound.
The LH A330 then suddenly jumped about 30-40 miles in a split second.

This was a one-off but doesn't explain the continuous lagging movement of EGCC departures positionally

Do you have the optional '*' showing in the aircraft label to see which tracks are live and which are Network?  Are you using the 5 minute delayed Network, or real-time?

Is there a chance that you are getting a mixture of live and Network tracks and you are confusing which are which?  What happens if you deselect 'Get Flights From RadarBox Network' at the bottom of the Network aircraft list?
Title: Re: Radarbox delayed data after powered for a long time
Post by: Marpleman on January 01, 2010, 06:40:57 PM
Hi Allocator

Can't speak for homestea, but I'm currently not using the network as my 12 months are up :-(  , and cannot really justify the renewal at present for my use.

also when I'm looking at local traffic,I always took the network down to avoid confusion.

today's been fine - everything showing where it should

homestea,

Can you try another PC and see whether you see the same results?

After more than 2 years on the market we have never come across what you have described and the lack of response from others on the forum related to your issue seems to match that. This could be a particular machine issue which may have a USB hub issue.

Post by: RodBearden on January 01, 2010, 08:20:42 PM
homestea - I have the beginnings of a theory!

On the status line alongside the Hardware and Network status indicators theres a bit that says something like 150 Msgs/Sec (60).

When your display has got very slow, what sort of numbers are appearing there - can you give us an example or two?

Im in the USA, and near a relativly small international airport. so Im not getting as much traffic as the people in england, that said; right now mine says
 27 Msgs/Sec (6)

The reason I ask is that recently I saw the number in brackets (which is the number of compressed messages processed by the RadarBox) get a lot bigger than the first number (the number of messages received by the RadarBox).

When this happened, my grid and map got delayed by up to 5 minutes. The circumstances were that my processor had been greatly overloaded - CPU was clocking 100% for very long periods, and the messages were presumably stacking up in the box before the processor could accept them.

I'm just wondering if your problem could be down to an overloaded processor - have you used Task Manager to see if your processor is getting pushed to the limit?

Title: Re: Radarbox delayed data after powered for a long time
Post by: homestea on January 01, 2010, 10:15:50 PM
my processor is only at about 25-35% on average, so i dont think this is the problem.  Im thinking that it is a driver problem or conflict with my system.  I am running th radarbox on a laptop with a centrino 2 duo, windows 7 64bit, 4GB Ram.   I see the driver folder includes 2 subfolders (i386 and amd64) since I am running a Intel processor, should i be trying to install the drivers in the i386 folder, as i assume the amd folder is for AMD processors? 
Title: Re: Radarbox delayed data after powered for a long time
Post by: RodBearden on January 01, 2010, 10:25:34 PM
Ah well, so much for my theory, then - it's unlikely to be lack of resources on your machine.

It sounds like you've installed the right drivers, but it doesn't sound like a driver problem anyway.

Sorry - I've no more ideas.

I Just finished installing the radarbox on my girlfriends computer and I get the same results.  Perhaps my radarbox is faulty or maybe i am being too particular.  Her computer is a windows 7 64 bit laptop with an amd processor.  I consistantly get altitude reading in program on a departure climbout 500-1000ft different than the pilot is reporting. Unfortunatly I havent been able to check an ADS-B aircraft position because pretty much the only planes ADS-B equipped flying out of this airport are UPS and FedEX, and I havent seen any departures for those today.

I was looking and it appears that windows 7 has a default usb polling rate of 125hz, is this adequate for the radarbox signals or does it need to be increased?
Title: Re: Radarbox delayed data after powered for a long time
Post by: AirNav Support on January 02, 2010, 12:43:01 AM
Altitude is not the best way to compare for the following reasons:

1.) QNH Settings means the altitude being displayed is not what the aircraft is at
2.) ATC call outs while descending or climbing might lag behind the real value

You will need to look at positions.

I would agree with you about the altitude, but just before i typed this a gulfstream 4 was departing, reported 7000, the radarbor reported 5200, i then disconnected the usb and plugged it in again. so it was off for about 6-7 seconds, but the new altitude that was recieved was nearly 9500 (the correct altitude).  there is no way the radarbox would have reported this altitude had i not disconnected it and plugged it back in.  I wish i could resolve this problem.

Is there anyway to re-flash the current firmware on the radarbox hardware without sending it out for a warranty fix? I see that the data stream output by port 30003 shows the exact information that is being display in the radarbox program. This leads me to believe that it is either a driver problem, or a firmware problem, or the unit is defective. Please advise.

I recently "upgraded" to Windows 7 and have noticed that the aircraft positions seem to be updating slower than before my upgrade. This morning I noted something very odd - for a short period of time, perhaps a few minutes, when the aircraft postions updated they actually moved backwards on their flight path. To clarify - I mean they updated to show the position they would have been in perhaps 30 seconds previously.  Heading was as expected, and I hadn't noted the previous GS and ALT for comparison purposes, but after reading through this thread I now wonder if there is something amiss here. Will keep a close eye on it and report further if it happens again.

Yea I have also noticed this backward thing a couple times. Hopefully they will recognize it as a problem and come up with some sort of a patch.

Yep, RadarBox runs a treat on all of my PC's/Laptops, so I don't think that luck comes into it :-) It must be at least 3 years since I rebuild the main PC now:

AMD Athlon 64 Processor 3200+
2.00 Ghz
2.00 GB RAM
XP Home Edition (2002) with Service Pack 3

Right now running:

RadarBox live and real-time Network data - sharing my data of course.
PlanePlotter (uploading RB data to the PP network)
Spotify (Like iTunes, but it doesn't cost you anything!)
Airfoil - to broadcast music to my Apple Airport Express into the Hi-Fi)
Google Chrome

Just finished uploaded some photos from an SD card into Picassa and then editing them with Paintshop Pro 7

And RadarBox V3.13 runs like a well oiled machine in the background - hasn't missed a beat all day!

OK, so I'm boasting, but V3.13 really is the best version yet as far as I'm concerned.

Fact is other users are clearly having difficulty running ANRB s/w - be this due to recent revisions or otherwise I don't know. Upon reflection I do agree with your advice that "luck has nothing to do with it" - do you have any suggestions as to what may have something to do with it ?

I run the free CCleaner and Defraggler often.  CCleaner also takes care of registry scans to get rid of the rubbish left behind when programs are uninstalled.  I have plenty of free space on the HD used for running programs.  I have a secondary HD for storing static stuff - pictures and the like - and a USB backup drive that is only used by Norton Ghost for archives.

I use the latest version of AVG Free antivirus (Norton Antivirus is a pervasive monster) and the free version of ZoneAlarm takes care of the Firewall.

This thread is about homestea issue only. So far no one other than himself is seeing the issue. As we have mentioned after 2 years we have not heard of such an issue. This does sound like a machine issue or USB issue.

Regarding version 3.13, it has been a overwheming success with only a 3 minor isuses known to us. The vast 99% majority is extremely happy with it and have thanked us for our efforts. The 3.13 comments threads shows this.

Airnav,

Well done for issuing a warning ! As for me - I haven't stated that I have issues that I believe aren't being acted upon.  If I did I would already have contacted Airnav tech support.

My apologies if I have misunderstood something, but both myself and Marpleman (and who knows how many others) are experiencing anomalies that appear to be similar to those as reported by homestea. I'm sure you'll agree this forum thread is an approprate place to discuss the matter.

All the best

Anomalies are fine, they do happen. Aircraft transponders don't always send the correct information, aircraft flying backwards with incorrect heading has been seen before. If your machine is overloaded then all software will start to do weird things.

However going back to the issue mentioned in this thread this has not been seen by anyone else the way he describes it. Lets try and keep it to the thread subject.

homestea we ask you to do the following:

- Try another PC
- Compare with visual contact of aircraft arriving or departing and do not use altitude.
- Please remember some aircraft occasionaly give wrong positions so do not be confused by that.

- Compare with visual contact of aircraft arriving or departing and do not use altitude.
- Please remember some aircraft occasionaly give wrong positions so do not be confused by that.

Hello, I've tried installing radarbox on a different PCs, unfortunatly that machine is also running windows 7.  Positional data is off roughly the same on both computers.  This even further leads me to believe that it is a windows 7 driver issue, or a radarbox hardware issue on my unit.  

Also my computer is a high end gaming machine with no other applications running in the background so i know it is not overloading. t has over 2Gb of RAM free at all times as well as it only spikes at 20-35 % CPU max at any given time

Thank you for any help you may be able to provide

Here is a typical ADS-B jump as i am describing.  You see the gap in positions. This gap spans roughly 5nm, and the USB signal was only disconnected about 7 seconds.  if you do the math that would equate to about 2500 knots to cover this span in the amount of time the usb was disconnected, if everything was working ok.  

This error was accumulated with the unit only being on for half an hour or so.

homestea - sorry if this has been asked before - thread's getting long - but have you tried using a different USB cable?

Within the area of coverage of my polar diagram there are small parts that have very little or limited coverage.  At times I can watch aircraft get to a particular part of airspace, it doesnt move for a minute or so and then it jumps to where coverage resumes.  My antenna is in the roofspace and i would think that this is caused by the particular airspace being blanked out by a nearby roof joist.  Could this be what is happening to yourself homestea, something blanking out returns within your covered area.?.

No, When i made my photo, I waited for a stong ADS-B aricraft signal that was giving 1 second updates, I then unplugged and plugged back in as as soon as the radarbox reconnected it gave strong returns again, however with the huge jump in distance.  The area that the plane is shown in, also happens to be my strongest coverage area for my antenna.

Hi again homestea

Sorry to hear you're still experiencing problems. One thought - does the respective record of the aircraft "timeout" in "Myflights" when you experience the jump on screen,or does it remain as a legit tracking?

Just a thought :-)

If your antenna's view is not blocked towards the gap then I would assume your system is jammed by something and for some time. Could be high energy mobile phone transmission or wireless TV or so between 500 and 2500 MHz. Best take your friend's notebook and change your position to open field and check from there.

Im still trying to figure out exactly what is going on. It seemed that when i switched to a shorter new USB cable, the problem seemed to go away for a while. Then last night all of my flights were delayed again.  It may be a conflict with my wireless mouse, so i have disconnected it and will find out this evening if the mouse was causing conflicts.  I have been seeing more and more recently the backwards effect that was described by another user some posts back on this thread. I will report baack soon.

Well I've now ruled out the wireless mouse causing the problem, i still am getting a delay buildup.  This sure is getting frustrating! I hope i can eventually figure out what the issue is! I encourage everybody running a 64 bit machine on windows 7 to watch closely the called altitude by aircraft to departure control to see if you are getting a delay as well.  Also watch ads-b aircraft positions versus what you can see outside your window.  Also try unplugging the radarbox usb and re-connect it to see f you see a large "jump" in positions.  Hopefully there will be a fix somewhere, somehow.

Hi Homestea,

Did you manage to reach any conclusion regarding the problems you are/were experiencing ?  I have noted today on my reasonably high spec 32-bit Windows 7 machine that after ANRB s/w has been running for a few hours, the screen (both the map and the info )  are updating very slowly -,i.e. every 5-6 seconds, as opposed to the 1 second update set in preferences.  Also when attempting to select items, they did not select until several seconds passed. At the point I ran a couple of other programs which ran normally. A quick shutdown and restart of the ANRB s/w and it was updating and responsive as normal again. Sounds similar to what you were experiencing.  I'll keep a note of how long before it stutters from hereon, and also note the program memory usage both before/after the slow down. If this turns out to be an inherent Windows 7 problem then I guess it will become more prominent as others switch to Windows 7. We'll see.

After playing around with it a bit more, I discovered that version 2009 2.01 version of the software, I don't seem to get any delay problems. So for now I am using this older version of the program until a fix is found for 2010 v3.13.  Perhaps Radarbox 3D will work as well, but i hope that there will be at least some kind of trial, before i decide to spend that much money on a software update.

I take it back.... I guess i spoke too soon. My data is now getting laggy again, even with the 2.01 software. I don't know why it acts so randomly.

This can only be a PC/Operating system issue, otherwise this would have been seen loads of times by those who have been using V2.01 for so long.  Also, not seen during the extensive Beta testing periods.

It seems i may have resolved the problem for good now.  I upgraded my Windows 7 Release Client to the Retail Windows 7 ultimate (since the beta period is almost up). Since doing this my lag problems have gone away.  I'm guessing it was a driver confict or a bug in the windows 7 beta build 7100.  Ill post again if i get anymore lag problems, but it seems like i may be goo now.
