Hi all,
I've been tracking flights on the new SBS-1 system which takes
signals fron aircraft equiped with ADS-B.
More info;

Anyway, when tracking, I've noticed that sometimes
the ARRIVING aircraft position does not match up with the map.
They can be up to 1-2 nm off.
The strange thing is that the DEPARTING acf always seem to be
exactly where you would expect.
Not sure if the ADS-B sends the real GPS position or
if it's IRS calculated position thats being transmitted.
Not being a pilot, I'm just guessing this could maybe be
the IRS system drifting over time? Or is this just a SBS "bug".
Any thoughts?
Cheers,
M
