MLAT freeze on last fix

Post by kiwikieran » Sun Apr 08, 2018 10:30 pm

Hi,
I have a merged feed with a MLAT server and a ADS-B receiver.
When the aircraft is no longer in the MLAT server area and is being picked up only by ADS-B receiver it will show the last known position.
And will not clear of the map until it is no longer in any receivers view.
Is there something I am doing wrong?
I have MLAT checked for the MLAT server but not the ADSB receiver.

MLAT receivers have a much longer display timeout than non-MLAT receivers. This is because the interval between position messages on an MLAT receiver can be much longer than with a normal ADSB receiver.

The whole area of flagging MLAT receivers and setting timeouts for them will be getting reworked fairly soon.

Thanks, I fixed this by adding a JavaScript for if postable = true then delete the marker.
