Hey mm43 thanks for the updated graphic, though as I mentioned before the projection is wrong. You need to either correctly project the satellite ping radius on the map projection you have (it won't be a circle anymore) or use an azimuthal projection centred on the satellite (then you can use a circle for the ping distance). The equidistant projection you are using is only equidistant with respect to latitude (vertical) distance from the equator and not equidistant at any angle from a point (even if the point is at the equator).
