The Kinetic energy will be maximum when the satellite is closest to the central body (at perigee) and minimum when it is farthest from the central body (at apogee). Potential energy will be minimum when kinetic energy = maximum i.e., the satellite is closest to the central body (at perigee) and maximum when kinetic energy = minimum i.e., the satellite is farthest from the central body (at apogee).
