Hi Rob, > Not quite. The spares are at a lower altitude. This leads to a > slightly different nodal precession rate. This differential > precession is pretty low (less than 1 degree per day) for > satellites with high inclinations, so it can take quite a > while depending on the target plane. all the Iridium orbital planes drift at about -0.4 deg per day in RA, but the differential rate because of the lower altitude is only 0.01 deg per day. How long do you want to wait until two planes are equal?
