Is the local PiAware Skyview filtering as well?

I run Skyview locally as part of dump1090-fa on a RPi. Yesterday I thought I had noticed a rescue helicopter which wasn’t showing on Skyview. Yet, I found it on ADSBExchange.

Is Skyview even filtering the data coming straight from my local receiver?


But some MLAT results are anonymized or you feeder might not have been used for the MLAT position of that helicopter in which case you don’t get MLAT results.

Helicopters are hard to receive, often obstructed as they fly low and if they are in sight the signal can be very strong and overload your receiver.
