Orbital motion under continuous normal thrust
WebOrbital position vector, orbital velocity vector, other orbital elements. In astrodynamics and celestial dynamics, the orbital state vectors (sometimes state vectors) of an orbit are Cartesian vectors of position ( ) and velocity ( ) that together with their time ( epoch) ( ) uniquely determine the trajectory of the orbiting body in space. [1 ... WebThe general continuous-thrust problem requires integration of the Newto- nian equations of motion for the trajectory, which may comprise hundreds of orbits and is highly sensitive to small changes in the thrust pro le.
