Application of Extended Kalman Filter to Orbit Determiation
The extended Kalman filter was applied to an initial orbit determination problem done by non-linear weighted least squares method in order to improve the error ellipsoid.
Presentation
Please visit: https://portfolium.com/entry/extended-kalman-filter-in-orbit-determination for the presentation on how this code was developed.
Code
The main script can run on its own to generate the solution, but I have also included all the functions separately as well.
