Hi Folks,
I am not a GPS user as yet but have applied for it
through the Veterans Administration. Point of issue the
wattage used to talk to and bounce communications off the
moon is 1/4 watt. This is a weak signal with nothing to stop
it, however it still takes just over 4 seconds to get there.
I want a GPS system to navigate the streets. Why would
anyone want to use it in flight? Isn't that time to catch a
nap?

Hi Peggy,
Actually, receivers do send a weak reference signal as part
of the
process of ocking onto the proper frequency. This is a very
weak
signal, and I wouldn't think it would interfere with
anything, but I was
told by someone who knows a lot about avionics, that,
believe it or not,
the radio navagation systems on airplanes are not shielded
from
extraneous RF signals. That really surprised me when I
heard it, and I
wonder if it is still true after 9/11.

You know, this talk of the GPS on airplanes reminds me of my
last trip
to Portland on Southwest. I had no intentions of using the
GPS on the
plane, preferring to keep the battery ready for use on the
ground. But
during the flight attendants' information about what could
and couldn't
be used in flight, they said anything "that sends or
receives a signal"
couldn't be used during a flight. Obviously, a receiver
doesn't send,
but it does receive. I was wondering if the regulations
have changed
and people are just going by what they used to be, or if
perhaps our
flight attendant misinformed us. Just curious.
