Enabling Software-Defined Satellites with Edge AI
Software-Defined Satellites (SDSs) enable spacecraft to evolve on orbit through software, moving beyond fixed-function architectures toward adaptable, multi-mission platforms. Software-defined radios and reconfigurable sensors and onboard compute systems provide foundational flexibility, while the integration of artificial intelligence at the edge is critical to achieving true operational autonomy. This presentation examines how AI-enabled onboard processing allows…

Evaluation of Heterogeneous Data Fusion for Real-Time Agricultural Stress Monitoring in Small-Scale Farming Ecosystems
Smallholder agricultural systems represent a critical frontier for climate resilience strategies, yet they are often underserved by traditional remote sensing frameworks due to fragmented land parcels and low-frequency reporting. This research investigates an autonomous geospatial framework designed to synthesize multi-source satellite data, specifically Sentinel-2 MSI optical imagery and CHIRPS precipitation datasets, to detect and characterize…

IRIDE EAGLET-II LEOP: A New Operational Paradigm for Constellation Operations
The increasing adoption of satellite constellations in LEO orbit is driving new operational challenges during the Launch and Early Orbit Phase (LEOP) that becomes increasingly critical. Thousands of satellites are sharing the Low Earth Orbit, elevating the importance of phasing strategies and collision mitigation, which are now central topics in mission design discussions. This paper…

Lessons Learned from UPAEP’s AzTechSat-1 and Gxiba-1 Nanosatellites
This paper presents lessons learned during the development of the AzTechSat-1 nanosatellite (rule-based and driven by NASA methods) and the Gxiba-1 nanosatellite (documentation-driven and demonstration-oriented), both of which were influenced by NASA’s mission culture and JAXA’s Japanese methodology. Both missions are grounded in systems engineering (traceable requirements, subsystem decomposition, and controlled integration). Quality gates, including…

Multi-sensor architectures for thermal imaging missions
Among the innovative offerings that NewSpace companies bring to the space industry, one of them is constellations of thermal instruments. Thermal infrared (TIR) imagers are inherently more challenging to calibrate and geolocate than visible and near-infrared (VNIR) instruments due to: • their lower spatial resolution • higher sensor noise levels and, • scarcity of stable…
