[Amps] Need some help on a project

[Will Matney]

David,

Believe it or not, I had way more help from here. I tried several places like leapsecond.com, etc and never heard back. I found the accuracy of these to be as good as or better than a cesium standard, especially over the long term since they're calibrated constantly. If the satallites gets off one hair the Naval observatory corrects it with the 60 cesium clocks, maser clocks, etc that they have running. The labeled accuracy of the Motorola GPS standard I bought was 5 ppb or;

5 ppb = 5/1,000,000,000 = 0.000000005 = 0.0000005% accuracy

Thanks to all who replied, it was a big help.

Best,

Will
