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?
