There are no polar orbits in GPS.  There are 6 such orbits with all of
them inclined by 55 degrees or so from the equatorial plane and
shifted 60 degrees (6 x 60 = 360) from one orbit to another.  <shrug>

That is irrelevant.  The bottom line is that you as a professor are
totally clueless and irresponsibly ignorant about even Newtonian
mechanics.  <shrug>

You should not have passed your first year physics course.  <shrug>

Of course, you are no professor but a children’s book writer.  No
professor would agree with the likes of DAVE and Dono, the symbols of
gross ignorance.  <shrug>
