An aerostable drag-sail device for the deorbit and disposal of sub-tonne, low earth orbit spacecraft [PDF]
, 2006 There is an increasing amount of debris in low Earth orbit arising from the disintegration and collision of old spacecraft which have not been removed from orbit. A ‘bolt-on’ deorbit device to be attached to new spacecraft is therefore proposed, which

Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Incorporating geosynchronous Earth orbit (GEO) and low Earth orbit (LEO) satellites can extend communication services far beyond the reach of terrestrial infrastructure. A key enabler of such architectures is the establishment of inter‐satellite links (ISLs) between LEOs and GEOs to support bidirectional communications.
