Did you check the GPS Nav Center from USCG? They put up advisories on
GPS testing. They look like this:
http://www.navcen.uscg.gov/gps/gpsno...terference.pdf

If any of the testing areas are close, you have an answer. If there
was a magnetic storm, it could explain it, too - see space weather (I
doubt it right now, the sun is very quiet).

They also have prediction of dop - dillution of precision, or
accuracy, at http://www.navcen.uscg.gov/gps/pdop.htm (lower is
better).

If you report your gps problem at http://www.navcen.uscg.gov/gps/default.htm,
they will generally get back to you and tell you why there was a
problem.

On my last two flights at Marfa Texas May 24 and May 10 I have lost
GPS navagation fixes for a few minutes on both flights. *I have two
GPS receivers (cambridge GPS/Nav and a lx-7000) both units lost their
fix at the same time and came back together. *Both flights are up on
the OLC if you want details. *Anyone else have the same experience?
Is it anything I can fix?
