Flight Performance Handbook for Orbital Operations: Orbital Mechanics and Astrodynamics Formulae, Theorems, Techniques, and Applications

, 1961
This handbook provides parametric data useful both to the space vehicle designer and mission analyst. It provides numerical and analytical relationships between missions and gross vehicle characteristics as a function of performance parameters.

Energy-conserving methods for Hamiltonian boundary value problems and applications in astrodynamics

, 2015
We introduce new methods for the numerical solution of general Hamiltonian boundary value problems. The main feature of the new formulae is to produce numerical solutions along which the energy is precisely conserved, as is the case with the analytical ...

Long term nonlinear propagation of uncertainties in perturbed geocentric dynamics using automatic domain splitting

, 2014
Current approaches to uncertainty propagation in astrodynamics mainly refer tolinearized models or Monte Carlo simulations. Naive linear methods fail in nonlinear dynamics, whereas Monte Carlo simulations tend to be computationallyintensive. Differential

Using mission analysis software GMAT to develop skills in astrodynamics

, 2017
Learning about the geometry and kinematics of orbital motion (or 'astrodynamics') is challenging due to its 3D nature. To address this, the University of Bristol have developed 3D orbit visualization exercises using a free NASA tool called 'General ...
