Aircraft vanishes on merged feed but appears on nearby rx

Post by darrylcn »

Hi, I have an odd issue where an MLAT helicopter based near me won’t show on my merged feed. If I choose the closest receiver to it however (this receiver is in said merged feed), the aircraft reappears. It’s as if that receiver, even though it’s in the merged feed, isn’t sending aircraft when that merged feed is selected. These helicopters fly low often, but a few different receivers must be picking them up or they wouldn’t MLAT at all. Can anyone suggest what I can do to fix this, if anything? Thank you.

Hey,

I'm facing the same issue. When I select the specific reciver, I can see the aircraft, but not in merged feed. The heigth is not relevant in my case.

Cheers,
Pakon

It’s very strange. I feel like a receiver is either in a merged feed and passing data or is not, but maybe there’s a configuration I’m not seeing.

Edit - I recreated a merged feed with just that receiver and my own and it’s showing everything. I’ll add more over time but this is a sort of fix for now.

Good point about the version. I’m on 2.4.3.36292. Hoping I can fix this without an update since otherwise it works perfectly. What version do you folks have?

Hey,

since yesterday:
v3.0.0-preview-5 Linux / MacOS Mono Tarballs
Released 07-MAR-2021
I will have a look, whether the issue still exists.

But in this time, you may open a bug ticket here: https://github.com/vradarserver/vrs/issues

Hey,

the issue still occur in my version. I could see that the position was calculated with mlat.

// Edit:

Found another Aircraft, also calculated with mlat. Only was showing when I choosed the "correct" receiver.

I will open a bug ticket.

// Edit2:

https://github.com/vradarserver/vrs/issues/43
