[time-nuts] Fw: Skytraq / GPS Almanac

[Nick Sayer]

I don’t have any SkyTraq navigation modules, but I power cycled a couple of my clocks (with the timing modules) and they came back up as they usually do, so I can tentatively confirm that in survey-and-hold mode they don’t appear to have any problems getting a fix. TBD is vetting the results to insure there’s no loss of accuracy, but I haven’t seen any weirdness from any of my GPSDOs at least.
