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.
