Quantifying Migratory Bat Movements in Central Europe Across Seasons and Years Using a Vertical‐Looking Radar

Remote Sensing in Ecology and Conservation, EarlyView.
Vertical‐looking radar provides a first multi‐year analysis of migratory bat phenology in Europe. Bat activity was lowest in winter, increased from spring, and peaked in summer, with similar timing of pre‐ and post‐maternity migrations across years.

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...

Path‐Based Deep Reinforcement Learning for On‐Board Routing in Satellite Constellation Networks

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Efficient usage of available network resources is a crucial factor for broadband services in interconnected satellite constellations. To meet required quality of service standards under heavy network loads, it is essential to optimize traffic distribution among the intersatellite links. To address this challenge, we propose an adaptive traffic
