Dear Fred,
Welcome to the fantastic world of celestial navigation!
With the little information you have give me, the problem could be that you are using:
- Hc as input instead Hs. (See my papers at my Web site).
- Other time different than UT1/UTC/GMT; GPS time, ...
Attached is an example simulated from your location at Texas. Try it!!!
If you want to learn celestial navigation, NavList is a nice place to be.
regards

Andres:
I am trying to learn celestial navigation and am confused
about something that I have noticed, which is this:
If I take my GPS coordinates and verify them with Google
Earth, then input them into the Nautical Almanac program at
the USNO, I get a data table for the time that I input for
celestial objects. If I then take that data for, in this
example, Polaris and Jupiter and plug those values into the
formulae (and programs) that are designed to give me my
location, the resultant position is always different than my
original GPS coordinates.
Why? What am I missing?
Thanks,
Fred
