I'm a little confused with Rendezvous Maneuver Sequencer.. How does it know my craft's and target's current positions? Is the position calculated from mean anomaly and epoch? I've checked wiki, but I'm not sure about my understanding about mean anomaly and epoch... Besides, I may have found a bug: After loading a SFS file in the Rendezvous Maneuver Sequencer, the Mean Anomaly and Epoch doesn't change!
