The present paper shows that various matrix expressions for the
solution to the relative orbital motion may be written in a much
simpler form, which was introduced for the first time in [6,7]. Instead
of using the orbital elements as constants of motion, this novel
approach is based on a tensorial frame-independent form of the
solution to the relative orbital dynamics.
The results deduced in the case of the relative spacecraft motion in
a gravitational field from a particle are generalized to the case of an
arbitrary central force field. An interesting geometric visualization
for the relative orbital motion in a central force field is presented.
