What are the limits of your hand held unit or what are the limits of
GPS in general.   I think GPS works as long as you are under the orbit
of the satellites.  The company I used to work for placed GPS on some
low orbit spacecraft, so say roughly 200 miles up and 18,000 mph but
I'd guess most hand held units would not work in those conditions
