Does position accuracy translate directly into timing accuracy? Is 30 meters still the right number for GPS? I thought they turned off the scrambling a while ago and L1 only is now good for 10 meters. >Folks might forget the Russian GLONASS system, which is very similar to >GPS and Galileo, has been around for over twenty years.

Are any GLONASS receivers available at a modest price? -- The suespammers.org mail server is located in California. So are all my other mailboxes.
