Spaceborne and ground-based sensor collaboration:Advancing resident space objects’orbit determination for space sustainability
《Astrodynamics》2024年第3期325-347,共23页Niki Sajjad Mehran Mirshams Andreas Makoto Hein 
The limited space around the Earth is getting cluttered with leftover fragments from old missions,creating a real challenge.As more satellites are launched,even debris pieces as small as 5 mm must be tracked to avoid ...

Dynamic analysis of tethered defunct satellites with solar panels
《Astrodynamics》2024年第2期297-309,共13页Rui Qi Yang Zhang Heng Jiang Rui Zhong 
A precise dynamic model for towing and removing a defunct satellite with solar panels in orbit using a tethered net often has low computational efficiency owing to the complex contact and collision between the net and...

Prediction and experimental verification of tether net entanglement for space debris capture
《Astrodynamics》2024年第2期223-236,共14页Kaito Kosuge Hirohisa Kojima 
This study involved simulations and experiments aimed at assessing the efficacy of a tether net in encapsulating space debris.The tether net was modeled as a spring–mass–damper system considering the influence of ae...

Real-time space object tracklet extraction from telescope survey images with machine learning被引量：3
《Astrodynamics》2022年第2期205-218,共14页Andrea De Vittori Riccardo Cipollone Pierluigi Di Lizia Mauro Massari 
In this study,a novel approach based on the U-Net deep neural network for image segmentation is leveraged for real-time extraction of tracklets from optical acquisitions.As in all machine learning(ML)applications,a se...

Limits of drag augmentation at spacecraft end-of-mission and a mitigation strategy
《Astrodynamics》2021年第2期109-120,共12页Emma Kerr Malcolm Macdonald 
This work received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No.687295.
An increasing number of objects are being launched into low-Earth orbit.Consequently,to avoid the possibility of future in-orbit collisions space object removal techniques are receiving attention.As one of the most de...

Dust in the Jupiter system outside the rings被引量：5
《Astrodynamics》2019年第1期17-29,共13页Xiaodong Liu Jürgen Schmidt 
the European Space Agency under the project“Jovian Micrometeoroid Environment Model”(JMEM)(Contract No.4000107249/12/NL/AF)at the University of Oulu,and by the Academy of Finland under the project“Earth and Near-Space System and Environmental Change”.
Jupiter is one of the major targets for planetary exploration,and dust in the Jovian system is of great interest to researchers in the field of planetary science.In this paper,we review the five dust populations outsi...
