Web2 days ago · It should read in 2 TLE files, then create Earthsatellite Objects with the skyfield package in python. After that it should search the TLE files for a specific timeframe. Then i want to plot the two satellites in this timeframe (make an orbit propagation) and calculate the minimum distance. ideally it should also mark the epoches which it used ... WebMar 31, 2024 · The SGP4 API has functions that will compute the predicted values of mean and osculating elements at any list of past or future times you choose, all from just one TLE. My recommendation, not just to you, but to everyone reading this, is to stop thinking that the numbers in TLEs are meaningful in themselves.
