Space Weather and Low‐Altitude Drone Economy

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Unmanned Aerial Vehicles (UAVs) are becoming integral to the emerging low‐altitude economy, operating primarily below 3,000 m for applications such as logistics, inspection, precision agriculture, and urban air mobility. The safe and reliable operation of UAVs depends critically on communication, navigation, and surveillance (CNS) systems ...

Mobility Management for the Low‐Altitude Economy: Latency‐Aware Handover Design

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper develops a latency‐aware mobility‐management framework for aerial vehicles operating in hybrid terrestrial non‐terrestrial networks. We formulate a MILP for optimal AV AP association and propose a greedy handover policy using predicted coverage, rate and handover latency.

Autonomous Parafoil Flaring Control System for eVTOL Aircraft

Aerospace
Reducing landing kinetic energy during emergency landings is critical for minimising occupant injury in eVTOL aircraft. This study presents the development of an autonomous parafoil control system for impact point targeting and flare control. A model predictive controller for a six-degree-of-freedom parafoil and eVTOL payload model was designed ...
