You just put one in a polar orbit and tell them to look at coordinates next time it is to pass that area over. Earth rotates under it meanwhile.

Pretty sure these satellites from far away are all in geostationary orbit.

GEO satellites never move. Only times they are moved out of its longitude is when they are decommissioned or relocated when absolutely necessary, which by the way takes months.

GEO satellites don't "pass over" anything by definition. They permanently float in the air 35786km above a designated spot along equator(complicated). So GP is clearly not talking about GEO satellites.
