Peraton was recently announced as the prime integrator for the
FAA's "Brand New Air Traffic Control System" (BNATCS) funded by
the One Big Beautiful Bill Act. One of the many tasks is
converting analog radios to digital, according to the Request for
Solutions issued this past August. I can't immediately find a lot
of specifics, but general AI inquiries indicate that ATC
communications will be transitioning to digital in the coming few
years, and a DoT fact sheet quotes 27,625 new radios will be
installed by the end of 2028. Is ATC going digital? Will some or
all of it be encrypted? How are we coordinating with the rest of
the world? Or am I misunderstanding what's going on?<br>
