astrojuanlu | * I said at the beginning that we would like to represent the area as a polygon. perhaps that's too ambitious and only useful for visualization purposes, and we could focus on:
the most relevant parameters of the coverage problem (i.e., ground-range angle Ξ, elevation angle Ξ΅, horizon-boresight angle Ξ·hor)

It is important to emphasize the magnitude of the ground range difference. The maximum deviation is20km andthis number can be considered significantly high for many applications, such as navigation mission and GNSS services,where the precision required is on the order of meters. Therefore, the spherical model is not completely wrong but itcannot be used in such accurate applications.
interesting!

astrojuanlu | well, fingers crossed :) https://twitter.com/poliastro_py/status/1280805427647778817 | 10:06:55 |

astrojuanlu | just discovered this! https://www.fatiando.org/boule/latest/changes.html#version-0-2-0 meuge do you think this is useful for us? | 13:22:23 |
astrojuanlu | looks more lightweight than SHTools | 13:22:29 |

astrojuanlu | and also https://www.fatiando.org/harmonica/latest/ π± | 13:31:24 |
meuge | Looks good!! But we should take into consideration that the package is in the early stages of design and implementation. That's what makes me doubt a little bit. | 14:19:59 |
astrojuanlu | you're right, I'm trying to understand the roadmap with the authors https://twitter.com/poliastro_py/status/1283036325118119949 | 14:27:52 |
astrojuanlu | the authors responded - I think we'll have to keep a close eye on them :) | 15:04:14 |

astrojuanlu | had some time to review the different repeating groundtrack algorithms from the information meuge posted, left a comment https://github.com/poliastro/poliastro/pull/984#issuecomment-661816355 | 12:09:07 |

jorgepiloto | Related with issue #497
While having a walk I though about the following: should we implement this under new poliastro.earth sub-package? We might create something like poliastro.earth.plotting in which a simple groundtrack.py module could be placed. This feature might enhance the use of the new module focused on Earth capabilities.

juanluastro | jorgepiloto I totally agree! | 17:24:34 |
jorgepiloto | Cool! I will add a comment in the issue π | 19:57:17 |

astrojuanlu | meuge: I think I'll be the first user of the new ground-range functions you implemented! so glad to have them in poliastro already π | 14:22:10 |
meuge | Amazing! If you any feedback as a user, we would try to implement it π | 17:19:16 |

astrojuanlu | hmm this is returning \Lambda_min and \Lambda_max, but I would have expected (negative, positive) in that case meuge ? | 18:00:46 |
meuge | I'll check that out. | 18:02:32 |
astrojuanlu | just in case, I used these values:
max_and_min_ground_range(480 * u.km, 50 * u.deg, Ξ·_center=0 * u.deg, R=6371.0088 * u.km)
| 18:04:16 |
meuge | It's returning \Lambda_max and \Lambda_min. Buy if you prefer, I can change the order or the returning parameters. | 18:26:57 |

astrojuanlu | woops! the order of the parameters in the docstring confused me π
