Hello,<br><br>Or it could be that they are testing their new satellites. The US has been working on deploying new generations of GPS satellites. Previously, you could get interesting ephemerides data from the satellite that was within 2 hours. Sometimes you could see 4 hours and now we have observed 6 hours ephemerides.<br>
There are a few changes coming in and I suspect this is just the new satellites test. I think it was number 5 or 25 that were changed recently.<br><br>Emilie Laffray<br><br><br><div class="gmail_quote">On 25 January 2011 08:52, Alan Mintz <span dir="ltr"><<a href="mailto:Alan_Mintz%2BOSM@earthlink.net">Alan_Mintz+OSM@earthlink.net</a>></span> wrote:<br>

Looks like this one extends as far north as SC, too.<br>
