I'll be flying along and will get a "GPS
Failure" announcement with
> loss of terrain info, plus DR (dead
reakoning) counter.
Jeff, you would want to turn to the satellite page
on the gx60.
I don't have a gx60 but on page 7-17 of the user
manual there' s a display page shown that shows the number of "healthy"
satellites.
Another approach would be to get a 396 and put the
antenna right where the gx60 one is and turn to the satellite page. This
will actually give you a map of the satellites and their signal strength so
you'll be able to determine the obstruction.
My gps antennas are under the glass (as opposed
carbon) part of the fuselage just in front of the vstab. I haven't seen
this problem. I would expect that large parts of the sky behind you are
obstructed by the cabin roof.
