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!
