Orbital State Vectors

In astrodynamics or celestial dynamics orbital state vectors (sometimes state vectors) are cartesian vectors of position and velocity that together with their time (epoch) uniquely determine the trajectory of a body in space.

Orbital State Vectors - Position Vector - Derivation
... The velocity vector can be derived from position vector by differentiation with respect to time An object's state vector can be used to compute its classical or ... used to quickly and easily estimate the object's state at any arbitrary time provided its motion is accurately modeled by the two-body problem with only small perturbations ... On the other hand, the state vector is more directly useful in a numerical integration that accounts for significant, arbitrary, time-varying forces such as drag, thrust and gravitational ...
