This topic was because the MLAT calculation and recording of the stats were not happening on the FlightAware side. More servers were add many months ago which fixed this problem.
Your site is showing ADSB and MLAT working fine. We don’t put synchronization numbers on the stats page but they do show up in your local logs.
Synchronization means that your site is synchronized with nearby receiver sites. You need synchronization with other sites for the timing calculations for MLAT per plane.
This is the stats for your site:
Number of planes for 12/7/2017
ADS-B count is the number of planes that have ADS-B transponders
MLAT count is the number of planes that have mode-S transponders that a MLAT position calculated
Other count is the number of planes that we couldn’t categorize (mostly mode-S planes without position calculations but there are a few other types)
If your MLAT wasn’t working your stats would be 0 for the MLAT count and all those planes counts would be in the Other category.
