The need for the extra dimension in Kustaanheimo–Stiefel (KS) regularization is explained by the topology of the Hopf fibration, which defines the geometry and structure of KS space. A trajectory in Cartesian space is represented by a four-dimensional manifold called the fundamental manifold. Based on geometric and topological aspects classical concepts of stability are translated to KS language. The separation between manifolds of solutions generalizes the concept of Lyapunov stability.

The Lissajous–Kustaanheimo–Stiefel transformation
The Kustaanheimo–Stiefel transformation of the Kepler problem with a time-dependent perturbation converts it into a perturbed isotropic oscillator of four-and-a-half degrees of freedom with
The theory of asynchronous relative motion II: universal and regular solutions
Two fully regular and universal solutions to the problem of spacecraft relative motion are derived from the Sperling–Burdet (SB) and the Kustaanheimo–Stiefel (KS) regularizations. There are no
Alternative Set of Nonsingular Quaternionic Orbital Elements
Quaternionic elements in orbital mechanics are usually related to the Kustaanheimo–Stiefel transformation or to the definition of the orbital plane. The new set of regular elements presented in this
Alternative Angle-Based Approach to the KS-Map. An Interpretation Through Symmetry and Reduction
The $\mathcal{KS}$ map is revisited in terms of an $S^1$-action in $T^*\mathbb{H}_0$ with the bilinear function as the associated momentum map. Indeed, the $\mathcal{KS}$ transformation maps the

This paper is a review, which focuses on our work, while including an analysis of many works of other researchers in the field of quaternionic regularization. The regular quaternion models of
Kustaanheimo–Stiefel transformation with an arbitrary defining vector
Kustaanheimo–Stiefel (KS) transformation depends on the choice of some preferred direction in the Cartesian 3D space. This choice, seldom explicitly mentioned, amounts typically to the direction of
The theory of asynchronous relative motion I: time transformations and nonlinear corrections
Using alternative independent variables in lieu of time has important advantages when propagating the partial derivatives of the trajectory. This paper focuses on spacecraft relative motion, but the
Regularized luni-solar gravity dynamics on resident space objects
Resident space object population in highly elliptical high perigee altitude (> 600 km) orbits is significantly affected by luni-solar gravity. Using regularization, an analytical orbit theory with


The KS-transformation in hypercomplex form and the quantization of the negative-energy orbit manifold of the Kepler problem
In a previous note we have shown that the KS-transformation, introduced by Kustaanheimo and Stiefel into Celestial Mechanics for the regularization of the Kepler problem, may be formulated in terms
Linearization: Laplace vs. Stiefel
The method for processing perturbed Keplerian systems known today as the linearization was already known in the XVIIIth century; Laplace seems to be the first to have codified it. We reorganize the
Interpreting the Kustaanheimo–Stiefel transform in gravitational dynamics
The Kustaanheimo–Stiefel (KS) transform turns a gravitational two-body problem into a harmonic oscillator, by going to four dimensions. In addition to the mathematical-physics interest, the KS

In this note the KS-transformation introduced by Kustaanheimo and Stiefel into Celestial Mechanics is formulated in terms of hypercomplex numbers as the product of a quaternion and its antiinvolute.
Time-Symmetrized Kustaanheimo-Stiefel Regularization
In this paper we describe a new algorithm for the long-term numerical integration of the two-body problem, in which two particles interact under a Newtonian gravitational potential. Although
Perturbation theory of Kepler motion based on spinor regularization.
A regularization of Kepler motion in the three-dimensional space Ä is developed using a simple mapping of a four-dimensional space R* onto Ä. In Ä* the equations of any undisturbed Kepler motion are
Orbit propagation in Minkowskian geometry
The geometry of hyperbolic orbits suggests that Minkowskian geometry, and not Euclidean, may provide the most adequate description of the motion. This idea is explored in order to derive a new

Time transformations involving momenta in addition to the coordinates are studied from the points of view of stabilization and regularization of the equations of motion. The generalization of
