Hi!

After a massive rewrite of the SatelliteToolbox.jl package, I finally managed to finish the first version of SatelliteAnalysis.jl after the revamp!

The idea was to split the original huge SatelliteToolbox.jl package into smaller ones, each solving a part required for satellite-related analysis. However, some functions did not fit anywhere because they required multiple parts to solve the problem. Hence, I created a package for those cases. In SatelliteAnalysis.jl, many algorithms use the entire SatelliteToolbox.jl ecosystem to perform analysis for space missions.

In the current version, we can:

- Compute the mission beta angle (used in thermal analysis).
- Compute the mission eclipse summary.
- Compute ground facility accesses and gaps to a satellite.
- Compute the ground facility visibility circle.
- Compute the ground trace of a satellite.
- Design orbits (Sun-synchronous, ground-repeating, frozen orbits).

I tried to add some examples in the documentation: Home ยท Satellite Analysis

For example, if someone wants to find all the possible Sun-synchronous, ground-repeating orbits between 700km and 800km that repeat their ground trace in 6 days, at most, to find the best one for their mission, all they have to do is:

```

In the following, I added some figures with the data obtained from the package that was plotted using Makie ecosystem (CairoMakie.jl, GeoMakie.jl, GeoJSON.jl):
