"Astrodynamics is the study of the motion of man-made
objects in space, subject to both natural and artificially induced
forces."
(Space Vehicle Design by Griffin and French)
The program for a recent AIAA/AAS Astrodynamics Specialist
Conference describes the various aspects of astrodynamics:
Satellite orbital dynamics, perturbation, and stability
Earth orbital and planetary mission studies, trajectory design
and optimization
Analytical, statistical, and numerical aspects of orbit determination
Autonomous navigation and rendezvous
Spacecraft attitude dynamics, determination, and control
Dynamics and control of large space structures, modeling of flexible
multibody dynamics, and estimation of distributed parameter systems
