I finally got around to reading the uBlox application note on their GPS  
receiver made specifically for timing.  Did I miss it or do they not offer  
TRAIM in their receiver?  I can't believe they would claim it to be for  
timing without TRAIM capability.  Regards, Doug, K4CLE

Oh, it's easy to find in the appnotes section on the ublox homepage:


BTW: if someone who has a better understanding of timing issues could
provide a list on how to improve that appnote, i'd be happy to contact
ublox and work with them to get us more and better information.
