Novel virtual satellite formation scheme for deterministic transmission

open access: yesTongxin xuebao, 2023
Although satellite formation flying could effectively support deterministic transmission due to its stable formation, but its formation control required significant real-time computational overhead and did not support flexible deployment for multi ...

Dynamic Network Formation for FSO Satellite Communication

open access: yesApplied Sciences, 2022
Satellite network optimization is essential, particularly since the cost of manufacturing, launching and maintaining each satellite is significant. Moreover, classical communication optimization methods, such as Minimal Spanning Tree, cannot be applied ...

The formation of regular satellites [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2004
Most models of planet formation envisage that early protoplanets were encompassed by a dusty gaseous disc. A simulation of planet formation by the capture-theory model has shown the formation of such a disc and suggests that its mass was close to that of the protoplanet and that it was a few au in extent.

Robust Satellite Formation Flying Controller Design Subject to Communication Delays

open access: yesIEEE Access, 2020
A robust control method is proposed to address the satellite formation flying problem subject to communication delays. Each satellite dynamics involves nonlinear dynamics, parametric uncertainties, and external disturbances.

Tidal Truncation of Circumplanetary Disks Fails above a Critical Disk Aspect Ratio

open access: yesThe Astrophysical Journal, 2023
We use numerical simulations of circumplanetary disks to determine the boundary between disks that are radially truncated by the tidal potential and those where gas escapes the Hill sphere. We consider a model problem, in which a coplanar circumplanetary

Universal adaptive control of satellite formation flying [PDF]

open access: yes, 2005
In this paper, a new universal adaptive control scheme for satellite formation flying is developed. The underline idea of our design is to combine the domination design and the monotone adaptive gain.

Self-organising satellite constellation in geostationary Earth orbit [PDF]

open access: yes, 2015
This paper presents a novel solution to the problem of autonomous task allocation for a self-organizing satellite constellation in Earth orbit. The method allows satellites to cluster themselves above targets on the Earth’s surface.
