AstroCoords.jl

This package is intended to be a one stop shop for all things related to astrodynamics coordinate systems. In addition to being non-allocating and highly performant all transformations found here are also differentiable with compatibility with a number of different automatic and finite differencing schemas.

Currently this package implements:

• [x] Cartesian
• [x] Keplerian
• [x] Delaunay
• [x] Modified Equinoctial
• [x] Spherical
• [x] Cylindrical
• [x] Unified State Model
  • [x] USM7
  • [x] USM6
  • [x] USMEM
• [x] Milankovich
• [ ] J2 Modified Equinoctial
• [ ] EDROMO
• [ ] Kustaanheimo-Stiefel
• [ ] Stiefel-Scheifel

This package may eventually support Attitude Coordinates as well.
