Earth Centered Inertial Frames (Equatorial and Ecliptic) | Orbital Mechanics with Python 39
This video covers the definition of the equatorial and ecliptic Earth centered inertial frames. The visuals are from NASA's SPICE-Enhanced Cosmographia software. Let me know if you'd like me to use Cosmographia more in future videos.
The two main Earth centered inertial frames are the equatorial and ecliptic. Both of them share a common X-axis pointing toward the vernal equinox at the J2000 epoch. This video goes into the details of how the equatorial and ecliptic planes are defined, and how you use that information to define the reference frames.
