Sorry I deleted my comment because I had already discovered the answer.
(I asked what the meaning was when an orbit is written as XXXxYYYkm.)
From my reading of both articles together, I'm pretty you're correct - it's the interval that the satellite's altitude moves between (ie the axis's on the ellipse around the Earth, like you say)
- eternauta3k 14y agoMinor correction, the apogee and perigee are not equal to the semimajor and minor axes because the Earth is in a focus of the ellipse.
