1. The problem statement, all variables and given/known data A GEO spacecraft crosses the earth’s equatorial plane when its true anomaly is 30 deg. The eccentricity of the orbit is 0.1 and its initial inclination is 5 deg with respect to the equator. What minimum velocity increment is required to transfer this GEO to an equatorial orbit? 2. Relevant equations e=.1 theta=30 degrees i=5 degrees cos E=e+cos(theta)/1+e*cos(theta) deltav=2*v*sin(i/2) 3. The attempt at a solution Not sure where to start. I am thinking I begin with the equations above. I think it is a plane transfer but not sure how to do it.
