Tangent-impulse transfer from elliptic orbit to an excess velocity vector

Vector Fields Tangent to Foliations

We investigate in this paper the topological stability of pairs (ω,X), where ω is a germ of an integrable 1-form and X is a germ of a vector field tangent to the foliation determined by ω.

An Operator Approach to Tangent Vector Fields Processing Supplemental Material

Lemma 2.1 Let V a vector field on M and let T t F , t ∈ R be the functional representations of the diffeomorphisms Φt V : M→M of the one parameter group associated to the flow of V . If D is a linear partial differential operator then DV ◦D = D◦DV if and only if for any t ∈ R, T t F ◦D = D◦T t F . Proof Let p ∈ M and f ∈ C∞(M) be a smooth function. If V (p) = 0, then Φt V (p) = p and DV ( f )(p...

Angular velocity nonlinear observer from vector measurements

This paper proposes a technique to estimate the angular velocity of a rigid body from vector measurements. Compared to the approaches presented in the literature, it does not use attitude information nor rate gyros as inputs. Instead, vector measurements are directly filtered through a nonlinear observer estimating the angular velocity. Convergence is established using a detailed analysis of th...
