Impact of Atmospheric Turbulence and Pointing Error on Earth Observation
Celia Sánchez-de-Miguel, Antonio M. Mercado-MartÃnez, Beatriz Soret +2
Earth Observation (EO) imagery is often degraded by atmospheric turbulence and pointing jitter; yet, these effects are rarely considered in datasets used to train AI-based detectio…
Statistical Analysis for Energy-Efficient Satellite Edge Computing with Latency Guarantees
Nicolai Dalsgaard Lyholm, Beatriz Soret, Tijana Devaja +3
Being able to provide latency guarantees for orbital edge computing applications through Low Earth Orbit (LEO) satellite constellations is a major milestone for their integration i…
Edge Intelligence for Satellite-based Earth Observation: Scheduling Image Acquisition and Processing
Beatriz Soret, Antonio M. Mercado-MartÃnez, Antonio Jurado-Navas +4
Modern Earth Observation (EO) missions generate massive volumes of imagery that challenge existing downlink and ground-processing capabilities, particularly for time-critical appli…
Learning Decentralized Routing Policies via Graph Attention-based Multi-Agent Reinforcement Learning in Lunar Delay-Tolerant Networks
Federico Lozano-Cuadra, Beatriz Soret, Marc Sanchez Net +2
We present a fully decentralized routing framework for multi-robot exploration missions operating under the constraints of a Lunar Delay-Tolerant Network (LDTN). In this setting, a…
Scheduling Agile Earth Observation Satellites with Onboard Processing and Real-Time Monitoring
Antonio M. Mercado-MartÃnez, Beatriz Soret, Antonio Jurado-Navas
The emergence of Agile Earth Observation Satellites (AEOSs) has marked a significant turning point in the field of Earth Observation (EO), offering enhanced flexibility in data acq…
An energy-efficient learning solution for the Agile Earth Observation Satellite Scheduling Problem
Antonio M. Mercado-MartÃnez, Beatriz Soret, Antonio Jurado-Navas
The Agile Earth Observation Satellite Scheduling Problem (AEOSSP) entails finding the subset of observation targets to be scheduled along the satellite's orbit while meeting operat…
