In this paper we develop a methodology based on ballistics to estimate the landing footprint associated with the powered terminal descent phase of a Mars soft landing.
In this paper we present a solution to the formation initialization problem for N distributed spacecraft located in deep space. Our solution to the FI problem is based on a three-stage sky search procedure that reduces the FI problem for N spacecraft to the simpler problem of initializing a set of sub-formations. We demonstrate our FI algorithm in simulation using NASA's five spacecraft Terrestrial Planet Finder mission as an example.
This paper provides a comprehensive survey of spacecraft formation flying guidance (FTG). Here by the term guidance we mean both path planning and optimal, open loop control design.
In this report we provide a vectorial derivation of the equations of motion characterizing the dynamite behavior of both ideal and non-ideal vibratory micromachined gyroscopes.
In this paper we develop the coupled orbital/attitude dynamics of a multi-body solar sail spacecraft (sailcraft) under the gravitational attraction of a single central body.
