Mappings in Astrodynamics [PDF]
Symposium - International Astronomical Union, 1992 We review mappings mainly devised for the study of the dynamics of comets and asteroids. An attempt of a typology according to the method used to devise the mapping and to its deterministic or stochastic character is made.

Improved shaping approach to the preliminary design of low-thrust trajectories
, 2011 This paper presents a general framework for the development of shape-based approaches to low-thrust trajectory design. A novel shaping method, based on a three-dimensional description of the trajectory in spherical coordinates, is developed within this ...
