Hi,

Im reading about satellite navigation and there is a term which i
cannot find a definition for- "mean equator"

this seems to be defined at a certain year.

My giuess is that the mean equator defines the inclination of the
sun's apparent elliptic path around the celestial equator.

???

any help is appreciated.

Regards,
Adam
