Can't find ground_station_accesses in v0.10.0

[esmith289]

This function was in v0.6.3 but can't find it in v0.10.0?

[esmith289]

same is true for list_ground_station_accesses

Hi @esmith289 !

The analysis functions are migrating to the package SatelliteAnalysis.jl.

I am changing the API a lot, and many breaking changes will happen in the near future. However, it will make everything much more consistent. Sorry about that.

By the way, ground_station_access is not ground_facility_access and the input/output is a lot different. You have now many options, including wrapping the result in a DataFrame to make further processing easier.

Thank you very much Ronan, this is a great package!Sent from my iPhoneOn Mar 24, 2023, at 1:59 PM, Ronan Arraes Jardim Chagas @.***> wrote: By the way, ground_station_access is not ground_facility_access and the input/output is a lot different.

Thanks @esmith289 !

I am really sorry for all those breakages. I have a much deeper knowledge about Julia language and its ecosystem than I had when the initial version of this package was released. Hence, I am doing a lot of improvements. I hope this phase ends soon :)

It’s great stuff that you are doing. Sent from my iPhoneOn Mar 24, 2023, at 2:37 PM, Ronan Arraes Jardim Chagas @.***> wrote: Thanks @esmith289 ! I am really sorry for all those breakages.

There are some issues we have been running into in regards to transitioning ground_station_accesses over to properly run in the SatelliteAnalysis package. Trying to alter the code that was in place for ground_station_accesses over to ground_facility_acesses create errors of "no method matching." I'm looking for a straight-forward way to translate the inputs of the ground_station_accesses to the new method (ground_facility_accesses) but documentation is limited.

Hi @sydbon !

I am in the middle of a rewriting of SatelliteAnalysis.jl. The current dev version has a new (more interesting) API. I think I will finish everything in one week or two. Until there, I suggest to keep using the old SatelliteToolbox.jl version.

But, if you want to try, add the development version of SatelliteAnalysis, and do:

julia> jd₀ = date_to_jd(2021, 1, 1)
2.4592155e6

julia> orb = KeplerianElements(
           jd₀,

           98.410 |> deg2rad,
           ltdn_to_raan(10.5, jd₀),
           π / 2,
           0
       )

Hi @esmith289 and @sydbon !

I just tagged v0.3.0 of the package https://github.com/JuliaSpace/SatelliteAnalysis.jl, which now contains the ground station algorithms. I also wrote the documentation about it. You can check it here:
