No offense taken, but I don't understand your comment. Below is a picture of the orbit track of the ISS. The orbit does not go any higher than ~52 degrees which is the inclination. Looking nadir, it won't see anything above the 52 degrees. It will only fly over the earth between +52 degrees (N) and - 52 degrees (S). Or am I wrong? Lower the 52 degrees to 28 degrees and a satellite will cover even less of the earth.
