How to show aircraft at correct position

[tarbat]

Just started using Virtual Radar Server, and generally impressed, as it comes closest to display I'm looking for.  The only problem I have is that the aircraft are displayed on the map too far north of their real position.  Take this EasyJet, just departed EGPE, but the aircraft symbol shows about 50 miles north of that on the map.

The aircraft icon is sitting on top of a stalk line, the bottom of which shows the aircraft location.

There's a VRS option to turn off the stalk.

Thanks, got it.  Much better.  Even better, able to show Planeplotter MLAT'ed aircraft in VRS - excellent.

I have to say that VRS is an excellent bit of software, great for replacing the Planeplotter display, which I've never got on with.

Where do I find this option please?

On the website - MENU - OPTIONS - AIRCRAFT - untick SHOW ALTITUDE STICK

With some adjustment, you can get a very good display setup in VRS

Configuration might be more accurate

Adjustment and configuration   Whatever it is, this is the closest I've got to an ANRB type display on any software, with some great configuration options that allow me to adjust exactly what I want to see.

Hello to all,
Today i observed an error when i tested one RTL dongle with setup : dump1090 --> modesmixer2 --> Basestation(version 1.84) --> VRS. Only
targets on ground , who located only few miles (7 nm) from my roof antenna , showing in wrong position thousands miles away! Over Antlantic Ocean!!!
How can i solve it?

[Anmer]

Were the only aircraft in the wrong positions those on the ground?

[APO1972]

Yes the most of ground targets has wrong position.

[Anmer]

Can you view the aircraft on Dump1090 without using ModesMixer2, BaseStation and VRS?  If you can, are they in the wrong position too?

[APO1972]

Now i m not home, I' ll check and tell you.As remember on Basestation screen all is in right position. In my mind i have maybe a silly though...maybe my windows country settings for the numbers, affecting VRS program?  You know i m Greek... The use of ","  and "."  are different than US and UK system.

Good morning , because one picture is more than 1000 words . See the attachments when the usb dongle feeding dump1090.
The first was a landing a/c , on the ground , see the strange constant -50ft altitude then after when speed is 0kts dissapeared.
The second another at parking stand , see the faulty longtitude.
At the third snapshot the same aircraft that the time became airborn so the coordinates as you can see fixed.

Thanks.

I am guessing that Dump1090 may be decoding On Ground messages incorrectly?  Since only a small percentage of users are close enough to airports to receive On Ground messages, this may have gone unnoticed.

I am aware that there were similar issues with other decoding solutions and we still see crazy aircraft movements on the ground on FR24 for major airports.
