Tue evening, I went to a talk on Auroras and Solar Storms. It was targeted as the general public so they didn't get into any technical details.
One of the pictures showed a GPS setup. They were using it to measure free electrons in the ionosphere. A friend found this in case anybody wants gory details: http://www.navipedia.net/index.php/Ionospheric_Delay -- These are my opinions. I hate spam. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
