Coupled attitude-orbit dynamics and control for an electric sail in a heliocentric transfer mission. [PDF]
PLoS One, 2015 The paper discusses the coupled attitude-orbit dynamics and control of an electric-sail-based spacecraft in a heliocentric transfer mission. The mathematical model characterizing the propulsive thrust is first described as a function of the orbital ...

Orbit Dynamics for Unstable Linear Motion [PDF]
Proceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 1996 A treatment is given of the orbit dynamics for linear unstable motion that allows for the zeros in the beta function and makes no assumptions about the realness of the betatron and phase functions. The phase shift per turn is shown to be related to the beta function and the number of zeros the beta function goes through per turn.

Dynamics of dual-orbit rotations of nanoparticles induced by spin–orbit coupling [PDF]
NanophotonicsSpin–orbit coupling (SOC) in tightly focused optical fields offers a powerful mechanism for manipulating the complex motion of particles. However, to date, such a mechanism has only been applied to the single-orbit motion for particles, while multi ...

Orbit Dynamics and Kinematics with Full Quaternions [PDF]
IFAC Proceedings Volumes, 2004 Abstract Full quaternions constitute a compact notation for describing the motion of a body in the space. An important result about full quaternions is that they can be partitioned into a unit quaternion (which describes the orientation with respect to a suitable reference), and a modulus (which represents the translational motion along the direction

Single-shot dynamics of spin–orbit torque and spin transfer torque switching in three-terminal magnetic tunnel junctions [PDF]
Nature Nanotechnology, 2020 Current-induced spin-transfer torques (STT) and spin–orbit torques (SOT) enable the electrical switching of magnetic tunnel junctions (MTJs) in non-volatile magnetic random access memories.

Some Special Types of Orbits around Jupiter
Aerospace, 2021 This paper intends to show some special types of orbits around Jupiter based on the mean element theory, including stationary orbits, sun-synchronous orbits, orbits at the critical inclination, and repeating ground track orbits.

International Journal of Aerospace Engineering, 2023 For space robots, it is difficult to track continuous time-varying manifolds on SE(3) by using traditional closed-loop control strategies, which are designed to track the position and the attitude separately.

Research on real-time reachability evaluation for reentry vehicles based on fuzzy learning
Open Astronomy, 2022 Accurate and rapid prediction of reentry trajectory and landing point is the basis to ensure the reentry vehicle recovery and rescue, but it has high requirements for the continuity and stability of real-time monitoring and positioning data and the ...
