I’m curious about the underlying mechanics of this. ( Off the top, this isn’t a complaint at all, I’m just a relatively new entrant into this space and curious. )
Doing a quick scan of the local piaware log, there doesn’t seem to be a significant change in the number of MLAT receivers synced with. Prior it looks like 75-85 , after more like 60-70. ( I can pull more accurate averages if that’s relevant. )
When I compare the number of MLAT positions reported vs the number of MLAT planes seen, the positions values starting 3/18 are about 50% for the same number of planes seen. Initially, I saw this thread and presumed that it was just the server rebalancing that was mentioned.
However, I also noticed another receiver about 40mi from me that had been offline for a while came back online on 3/17 as well, so I was very curious if there was a relationship between the two. I don’t recall if that effect existed before they were offline, as I was just getting started with this and playing with my setup a bit.
Just a small comparison snippet here, picked similar planes seen values.
(Date . MLAT planes / MLAT positions)
My site : 38758
3/13 . 1274 / 455,977
3/16 . 1275 / 417,098
3/22 . 1285 / 212,971
3/24 . 1253 / 199,321
Other site : 15876 (Offline until late day 3/17)
3/22 . 1361 / 516,657
3/24 . 1381 / 523,184
I know this isn’t apples to apples at all, but with two things changing at once, just got me curious. Wasn’t sure if another ‘busy’ station impacted MLAT in some way, or if this is just a function of the server balancing.
