Then the system would work as if covered by SSR without the cost of the as yet uncertified ADSB.
Why is ADSB "uncertified"? If it really is uncertified, one must only conclude that MLAT is also "uncertified". Who would "Certify it"?
Given ADSB is currently in use (high) (and low near the box sites), surely it must have some sort of certification/sign-off for operational use?
There still is no radar "replicating" standards, is that what you mean?
I understand that some MLAT sites were not secured, ie not leased correctly or sites without power etc. so the units were not deployed; some rumour about using some of the units for the SY PRM replacement project too.
Also heard issues with turning the current LT head off with or without MLAT use; but not clear about it. Something like turning the radar off before turning MLAT on.
