Sherical trig / solid geometry review

Can anyone recommend a good on line resource for review of basic
spherical trig and solid geometry. I'm interested in diving into the
math for determining location by knowing the distance to a set of points
(ie satellites) in space. I'm fine with solving systems of equations but
haven't touched solid geometry since 1/2 credit course in high school
forty years ago ;)

I doubt that you will find very much unless you buy a book or take a
course...

Most people would just go for the actual application that they are
interested in and then filter down from there...

But here's a link:

Note Map Projection, Geodetic Datum, and Coordinate Systems...

And here's a one pager:

And, I haven't found a package that does exactly what I want and
presents the results exactly the way I want. So I'm going to roll my
own. Also I have a very large curiosity bump.


Have that.


That's the point of view I was looking for. It doesn't have everything
but jars me in the right direction to be able to derive the rest of what
I want. Thanks.

Mr. Watkins nicely summarizes my point of view saying:
"This lack of recent texts on spherical geometry and trigonometry is
puzzling because the use of computers should shift the emphasis from
numerical computation to theory. This page is an attempt to present
derivations of important results from spherical geometry and trigonometry."

Yeah...just work towards a degree...


Well add the subject Geodesy...
