re: Roderick Wall
That's what I was hoping for.
Okay if I can find those 5 for example, I could choose one of them.
Maybe the one on the right and keep using that one for reference.
Or, maybe choose the brightest, ASC2 and use that as the reference.
I guess it will only work for half of the earth, we would need another
geostationary satellite for the other side, but I think that would be
easy enough also.
We could just abandon the GMT system and create a system for
individuals, with personal prime meridians based on where you come from.
Locate a satellite, make its' north/south east/west inclinations
equal zero and navigate half of your world and back again by measuring
the inclination deviations.

Hi Brent,
The following links shows a photo taken of five geostationary satellites
(using 5 hour exposure). I would have thought that there would be more
than five satellites all in a line, why only five?

So with the link provided by Richard Langley I can see geostationary
satellites with a telescope:
<http://www.satobs.org/geosats.html>
I think if I did that I could determine my latitude by measuring the
angle of the satellite from the horizon on my north/south meridian.
But now I can also determine my longitude by measuring the angle of
the satellite from my east/west horizon. Of course it will be in
relation to the satellite, not to the Greenwich meridian.
Does this sound correct?
If so, I could navigate a boat with just a telescope, a compass and a
protractor and not need a clock to tell me Greenwich Mean Time?
