When a satellite is orbiting the earth in an elliptic orbit, it has a certain inclination with respect to the earth's equator. The usual way to change the inclination is perform a maneuver by firing the rocket engines at the periapsis of the ellipse. This then forces the satellite into the desired inclination. There is a substantially more fuel efficient way to change the inclination. This is done by an indirect route by first doing a maneuver to bring the satellite to the moon on a BCT (Ballistic Capture Transfer). At the moon, the satellite is in the s...

[ What is claimed is:] [1.] A method of changing an inclination of an object by generating a combination operational ballistic capture transfer (BCT) for the object emanating substantially at earth or earth orbit to arrive at a weak stability boundary (WSB) or WSB orbit at or near the moon or moon orbit and generating an operational ballistic ejection transfer (BET) for the object emanating at the WSB or the WSB orbit to return to the earth or the earth orbit, using a computer implemented process, comprising the steps of:(a) implementing a forward target...
