Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback
Journal of Field Robotics, EarlyView.ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.

Three‐Year Propagation Experiment at Ku‐, Ka‐, and Q‐Band in French West Indies
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT From January 2021 to December 2023, the Office National d'Etudes et de Recherches Aérospatiales (ONERA) and the Centre National d'Etudes Spatiales (CNES) conducted a three‐year Earth‐space propagation measurement campaign in Guadeloupe. The experiment used beacon receivers deployed in Pointe‐à‐Pitre airport to record signals at 11.2, 19.7, and

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

BROADCAST TELEVISION: BROADCAST GEOGRAPHY?
European Journal of Geography, 2011 Television plays an important role in how the public both understands and takes an interest in geography. As geographers, if we are to maximise the opportunities provided by television to promote geography, we need to understand how it is developing in the 21st century. The first part of this paper examines some of the concepts currently applied to the

International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Low Earth Orbit (LEO) satellite constellations offer unprecedented opportunities for global broadband connectivity but pose significant beamforming challenges due to rapid platform motion and stringent onboard hardware constraints. Fully digital architectures, while optimal in theory, remain impractical for satellite payloads, motivating ...
