Hera Orbit Determination Covariance Analysis of Didymos Binary Asteroid with the Full Two-Body Problem
Edoardo Gramigna, Riccardo Lasagni Manghi, Marco Zannoni +7
Standard planetary radio science analyses may be inadequate for accurately interpreting data from the Hera mission at the Didymos system due to the anticipated challenge posed by t…
Efficient trajectory design for distant planetary orbiters
Francesca Scala, Ioannis Gkolias, Camilla Colombo
Starting from the Hamiltonian representation of the dynamics in \cite{rosengren2015chaos,colombo2019long}, this work proposes an innovative procedure to design fully-analytical man…
SELENA: Semi-analytical Integrator for Lunar Artificial Satellites
Christos Efthymiopoulos, Kleomenis Tsiganis, Ioannis Gkolias +2
The present report summarizes the main theory and implementation steps associated with SELENA (SEmi-anaLytical intEgrator for a luNar Artificial satellite), i.e. the semi-analytica…
The Perturbed Full Two-Body Problem: Application to Post-DART Didymos
Alex J. Meyer, Harrison F. Agrusa, Derek C. Richardson +19
With the successful impact of the NASA DART spacecraft in the Didymos-Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid…
Predictions for the Dynamical States of the Didymos System before and after the Planned DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +33
NASA's Double Asteroid Redirection Test (DART) spacecraft is planned to impact the natural satellite of (65803) Didymos, Dimorphos, around 23:14 UTC on 26 September 2022, causing a…
TEDGE-Caching: Transformer-based Edge Caching Towards 6G Networks
Zohreh Hajiakhondi Meybodi, Arash Mohammadi, Elahe Rahimian +3
As a consequence of the COVID-19 pandemic, the demand for telecommunication for remote learning/working and telemedicine has significantly increased. Mobile Edge Caching (MEC) in t…
A deep dive into the resonance: separatrices, manifolds and phase space structure of navigation satellites
Jerome Daquin, Edoardo Legnaro, Ioannis Gkolias +1
Despite extended past studies, several questions regarding the resonant structure of the medium-Earth orbit (MEO) region remain hitherto unanswered. This work describes in depth th…
The Excited Spin State of Dimorphos Resulting from the DART Impact
Harrison F. Agrusa, Ioannis Gkolias, Kleomenis Tsiganis +12
The NASA Double Asteroid Redirection Test (DART) mission is a planetary defense-driven test of a kinetic impactor on Dimorphos, the satellite of the binary asteroid 65803 Didymos.…
Dynamical taxonomy of the coupled solar radiation pressure and oblateness problem and analytical deorbiting configurations
Ioannis Gkolias, Elisa Maria Alessi, Camilla Colombo
Recent works demonstrated that the dynamics caused by the planetary oblateness coupled with the solar radiation pressure can be described through a model based on singly-averaged e…
Chaotic transport of navigation satellites
Ioannis Gkolias, Jerome Daquin, Despoina K. Skoulidou +2
Navigation satellites are known from numerical studies to reside in a dynamically sensitive environment, which may be of profound importance for their long-term sustainability. We…
Accurate modelling of the low-order secondary resonances in the spin-orbit problem
Ioannis Gkolias, Christos Efthymiopoulos, Alessandra Celletti +1
We provide an analytical approximation to the dynamics in each of the three most important low order secondary resonances (1:1, 2:1, and 3:1) bifurcating from the synchronous prima…
Towards a sustainable exploitation of the geosynchronous orbital region
Ioannis Gkolias, Camilla Colombo
In this work the orbital dynamics of Earth satellites about the geosynchronous altitude are explored, with primary goal to assess current mitigation guidelines as well as to discus…
Drift and its mediation in terrestrial orbits
Jerome Daquin, Ioannis Gkolias, Aaron J. Rosengren
The slow deformation of terrestrial orbits in the medium range, subject to lunisolar resonances, is well approximated by a family of Hamiltonian flow with degree-of-freedom.…
Hamiltonian formulation of the spin-orbit model with time-varying non-conservative forces
Ioannis Gkolias, Christos Efthymiopoulos, Giuseppe Pucacco +1
In a realistic scenario, the evolution of the rotational dynamics of a celestial or artificial body is subject to dissipative effects. Time-varying non-conservative forces can be d…
From order to chaos in Earth satellite orbits
Ioannis Gkolias, Jerome Daquin, Fabien Gachet +1
We consider Earth satellite orbits in the range of semi-major axes where the perturbing effects of Earth's oblateness and lunisolar gravity are of comparable order. This range cove…
The theory of secondary resonances in the spin-orbit problem
Ioannis Gkolias, Alessandra Celletti, Christos Efthymiopoulos +1
We study the resonant dynamics in a simple one degree of freedom, time dependent Hamiltonian model describing spin-orbit interactions. The equations of motion admit periodic soluti…
The dynamics of the elliptic Hill problem : Periodic orbits and stability regions
G. Voyatzis, I. Gkolias, H. Varvoglis
The motion of a satellite around a planet can be studied by the Hill model, which is a modification of the restricted three body problem pertaining to motion of a satellite around…
