This section provides the mathematical specification of all the computations in Nyx and the verification and validation results. You may independently re-run the V&V from the GMAT scripts if that strikes your fancy.

If you'd like to report an error, request additional details on some computations, or add a validation test case, please contact me at one of the links on the bottom of the page.

Refer to this page for all of the upcoming new features and this page for the list of known bugs.


This MathSpec was written from the Nyx source code: the code was inspected and the relevant equations rederived from this. Please also check the validation section of this website to see how Nyx was validated with the help of NASA GMAT.


Yay! You found the box which will detail the V&V for a given section. It's hidden by default to not overload the page with tables.
