Ground Tracks

Codes to compute and plot a satellite's Ground Tracks.

You are now following this Submission

The folder contains several scripts able to compute and plot the Ground Tracks of a satellite orbiting the Earth.
Features:
- unperturbed GTs (just Earth rotation shift)
- perturbed GTs (with second-zonal harmonics, J2)
- repeating GT for both unperturbed and perturbed case
- plot just 1 or, simultaneously, 2 GTs
