Hi! I need help with a problem regarding orbital maneuvre. The question is: You're doing a first-order analysis on a new satellite in an elliptical orbit with eccentricity e=0.20 and altitude 700 km. Can you design the orbit so that no maneuvers are necessary to maintain it? Where should I begin? I know that it is a polar orbit since the altitude is 700 km, and the inclination is then 90 degrees. J2 is approximately 10^-3 Thanks!
