Re: [time-nuts] WWVB & Eclipse

Hi I think we are both taking it as a given that the eclipse’s impact on the ionosphere will be “visible” even with a fairly simple setup. I guess that might qualify for a very loose definition of the term “hypothesis” in my case. I can’t speak for Tom. Bob > On Jul 13, 2017, at 6:24 PM,

Re: [time-nuts] WWVB & Eclipse

Tom, are some specific hypotheses being tested or is this purely exploratory? Bill On Thursday, July 13, 2017, Tom Van Baak wrote: > The trick is to just run the timing receiver in all-in-view mode > collecting 1PPS data against your house standard as usual, but also

Re: [time-nuts] WWVB & Eclipse

The trick is to just run the timing receiver in all-in-view mode collecting 1PPS data against your house standard as usual, but also capture all the binary message(s) where the per-SV Az/El/SNR and phase residuals are reported. This allows you to re-create the individual "1PPS" from each SV

Re: [time-nuts] WWVB & Eclipse

Hi If one perhaps knew the path of the eclipse in advance *and* had a GPS timing receiver that could be set somehow to look at a single satellite….. all one would need is a means of comparing the output to a stable reference to *possibly* observe something interesting. More or less: You know

Hi: There's a massive experiment relating to the strength of WWVB and a transmitter in Dixon California. https://www.washingtonpost.com/news/speaking-of-science/wp/2017/07/12/a-massive-atmospheric-experiment-is-planned-for-august-solar-eclipse/?utm_term=.4d7101b869f6

Re: [time-nuts] A milestone approaches

2038 could be an "interesting" year - on the 22nd of April, the MJD hits 65535 (2^16-1) ! On 12 July 2017 at 13:19, Tom Van Baak wrote: > Thanks for the notice. Add these to your list: > > 2147483648 0x8000 Tue Jan 19 03:14:08 2038 GMT (you survived) > > While
