Yes, and all are in the same equitorial orbit

Yes, and all are in the same equitorial orbit

This is the only orbital height where the ornital velocity coresponds to 360
degrees every 24 hours - keeping at one location obove the Earth at any
orbital inclination - the satellite would appear to movein a distorted
figure-8 in the sky, and would shine on the same spots of the Earth's
surface once per sidereal day.

Called "The Clarke Belt" after Arthur C Clarke, who proposed the
concept in 1945.
Yes, the same A.C. Clarke that is the science fiction writer.
