libraries - Which should I use: Python-sgp4, PyEphem, python-skyfield -

-

the landscape of python tools seem accomplish task of propagating earth satellites/celestial bodies confusing. depending on you're trying do, pyephem or python-sgp4 may more suitable. of these should use if:

  • i want ecef/eci coordinates of earth satellite
  • i want general sky coordinates of celestial object
  • near earth vs. far away objects
  • want use two-line element sets

do of these accomplish precise orbit determination? if not, go/what resources there out there precise orbit determination?

i kind of know answers here. instance, pod not part of of these libraries. these computations seem involved. pod many objects available igs. main reason ask documentation purposes. i'm not familiar python-skyfield, have hunch accomplishes these other 2 do. --brandon rhodes, await expertise :)
