I don't know really know the difference between a frame and a coordinate system. I'd proposed ECEF and ECI tags, do we need them? Frames seems to be the standard in meta but there is concern so any changes are on hold.

I'd always thought that ECI and ECEF were the same thing except one rotated and the other didn't. They were two cartesian coordinate systems centered on the geocenter with one inertial and one rotating with the planet.

But maybe it's much more complicated than that, it usually is!

Questions:

  1. Are ECI and ECEF both frames?
  2. Are ECI and ECEF both coordinate systems?
  3. In spaceflight lingo, is there a difference between a frame and a coordinate system?

Are ECI and ECEF both frames and/or coordinate systems? Is there a difference?
