[time-nuts] Loran in the US

Hi

If they are backing up GPS for telcom, then CDMA timing is the most likely
target. That gets them to 10 us max and < 1 us typical. Of course somebody
would have to buy the gear to actually *use* it to do any good... (yes I
could and have gone on and on about that topic).

Has anybody asked them how good time&freq they're trying to deliver ?

I would assume that they are aiming for a backup for GPS in
telecom-GPSDO context.

If so, frequency stability is priority number one and time is
probably just "better than 100msec" or so
