Re: anyone running GPS clocks in Southeastern Georgia?

As I understand it, they're trying to get the WAAS sat back online and
working properly after it went on walkabout some time ago. It's currently in
a nonstandard orbit while they work on it. I suppose it's just pure
speculation that they'd only be working on the WAAS service since the NOTAM
doesn't say anything about it, but if that were the case there wouldn't be
any effect to timing.
