Which time-nut will be the first to see PRN 32 on Feb 19?
I wonder what old GPS receivers won't be able to see it?

The U.S. military announced earlier this week that GPS satellite SVN23,
transmitting L-band code as PRN32, will be set to usable

Hi All
I've been offered a Racal 485-1, 1MHz frequency standard and distribution
system.
From the photo it's basically a Racal 1MHz ovened oscillator with a 12 way
distribution section based on TO92 style plastic transistors.
I don't know that it's something I'd use these days as a lab

So-- Is PRN the same as SV as given for each
GPS bird being tracked by my Trimble T-Bolt?
Thanks!!
My Thunderbolt (nor any of the others, of course) cannot see this one at
present, but TBolt Mon is showing a yellow button indicating incomplete
