Also, GPS L2C and L5 signals is already there.
AFAIK there is no satellite with L5 capabilities in space yet.
Also L2C is still marked as unhealthy.

There are at least 2 satellites radiating L5, maybe more. We've
received and processed the signals (and those from L2c) on the JPL
software receiver on ISS. (making a first.. first triband receiver in
space, etc.)
I'm pretty sure the L2c signals have been radiated for a while. If
they're not marked "good", it's probably because the formal validation
process hasn't completed.
(in fact, a quick trip to gps.gov says for L2C "Pre-operational signal
broadcasting from 14 GPS satellites (as of November 7, 2014)" and for L5
"Pre-operational signal broadcasting from 7 GPS satellites (as of
November 7, 2014)"
So, not a whole constellation, but the signals are there.
