[gps-talkusers] A general question

As a user of the Sendero product for less than two weeks along 
with my recently acquired Mpower BT, I am enjoying learning the 
uses of this marvelous toy.

I recently took it on a jet plane from Minneapolis to Sacramento 
which prompts me to ask this question.  I had the window seat on 
this flight and fastened the Holux 236 to my shirt collar, so it 
was relatively close to the window.  It took the Holux perhaps 
two minutes to acquire a fix, and signal quality was only fair 
with five satellites as I recall.  And now for the question.  Why 
did neither the A command nor the C command yield any 
information?  I do not recall verbatim the response, but the 
bottom line was that it could not seem to get a fix.  Conversely, 
I was able to determine both speed and altitude.  So the question 
is why could I not ascertain the nearest city or LL coordinates? 
I am certain there is a logical reason for this, but I am too new 
at this sort of thing to understand the fine points.

Thanks for any responses.
