Most commercial geostationary communications satellites must maintain their orbital positions to within +0.05° of arc. If a geostationary satellite meets this condition (i.e., it has an apparent motion +0.05° of arc N-S and +0.05° of arc E-W, as measured from the center of the earth), calculate the maximum range variation to this satellite from an earth station with a mean elevation angle to the center of the satelite's apparent motion of 5°. You may assume that the equatorial and polar diameters of the earth are the same.
