This program is intended to simplify converting orbital parameters from a plane-of-sky reference frame to an ecliptic one, e.g. for use in Celestia. Based on code released by @ajtribick in April 2021.
There are two ways to run the program. On any operating system, you can install Python 3 and the scipy and FreeSimpleGUI modules, and run the program from IDLE or the command line. For Windows users, there is also a Windows executable available under "Releases".
