71Orbital state vectors — In astrodynamics or celestial dynamics orbital state vectors (sometimes state vectors) are vectors of position ( ) and velocity ( ) that together with their time (epoch) ( ) uniquely determine the state of an orbiting body. State vectors are… …
72Mean longitude — In astrodynamics or celestial dynamics, mean longitude is the longitude at which an orbiting body could be found if its orbit were circular, and free of perturbations, and if its inclination were zero. Both the mean longitude and the true… …
73Orbital inclination change — is an orbital maneuver aimed at changing the inclination of an orbiting body s orbit. This maneuver is also known as an orbital plane change as the plane of the orbit is tipped. This maneuver requires a change in the orbital velocity vector… …
74Two-line elements — Orbital parameter for the SGP4 model (or one of the SGP8, SDP4, SDP8 models) are determined for many thousands of space objects by NORAD and are freely distributed on the Internet in the form of TLEs by Celestrak (http://celestrak.com/). Here the …
