I am trying to do a rendezvous based on a state vector (position and velocity) of one spacecraft and a position of a second spacecraft. I want to get a delta-V (x, y, z) to translate myself from the state vector position to the second position in some time, t (which I can calculate). Is this even possible? I know how to do Hohmann or Lambert using orbital elements, but using a state vector and a position vector is not something I'm familiar with. Thanks in advance.
