Perhaps more geodesy related is the Modern Navigation course at MIT. Lectures and other materials for the class are available via the Open Course Ware...

I am surprised someone has not attempted to pry out this monument. Not to give anyone any ideas...

I guess I was misled by the implied precision of the answers. BTW, if you remember the factor representing one second of arc in radians you can just m...

Thanks for posting this. Some of the images were particularly interesting. I did not see the name for the theodolite used before the adoption of the T...

Depending on where you are you might want to use an NGS calibration baseline. It will provide an accurate value for comparison. If you make observatio...

Why use plane trigonometry? Are you solving a right triangle? Use some basic geometry. Given a distance (R) and angle (theta) solve for the arc length...

From the top few recommendations from Google I like those listed below.. You might also want to examine the documentation for the software package GLO...

The Elithorp book mentioned in your other thread has a nice discussion of th various radii used in geodetic computations. It includes some good illust...

EFB, Unfortunately I do not have the document to which your link refers.With respect to the issue of the incompatibility of a, b and f-inverse, I alwa...

Take a look at the chart linked herebr>You will see that even the ultra-rapid orbits are extremely good. Unless the CORS used are extremely distant, I...

Perhaps thinking about this issue as a leveling circuit might help. Running levels between four points A, B, C and D in the following manner: A-...

Not exactly sure if you are saying you manually typed in CORS coordinates or whether there is an option in the program to retrieve them from the NGS s...

FWIW, I recommend the book " Geodesy for GIS and Geomatics Professionals," by Elithorp and Findorff. It can be ordered through: I used it in an underg...
