Geometric Characterization of LEO–GEO Inter‐Satellite Links for Bidirectional Communications

open access: yesInternational 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.

Renewable Resource Curse Hypothesis: Could Renewable Resources Foster Sustainable Development?

open access: yesSustainable Development, EarlyView.
ABSTRACT This study explores whether the resource curse hypothesis applies to renewable energy by introducing a novel metric of renewable resource rent. Using a panel dataset of 46 countries (2010–2022), we define renewable rent as the product of electricity generation and the gap between industrial electricity price and levelized cost (LCOE).
