A Data Fusion Framework for Real-Time GNSS Availability Assessment Under Combined Space Weather and Terrestrial Interference
Global Navigation Satellite Systems (GNSS) have become critical infrastructure for autonomous platforms across space, maritime, and ground domains. Historically, GNSS accuracy degradation was primarily attributed to natural phenomena—ionospheric disturbances, scintillation, and solar activity. However, modern operational environments increasingly face terrestrial threats including intentional jamming, spoofing, and regional denial zones. Current mission planning tools address these…

FOCUS: Free-space Optical Communications Unit for Satellites
Laser and optical communication terminals offer tremendous opportunity for high-speed (>1 Gbps), highly-secure, inter-satellite and satellite-to-ground global communications. Traditionally, high size weight and power (SWaP) requirements have created challenges in realising COTS products, as well as, the application of such devices in small satellites such as CubeSats. A academic-industry consortium led by Northumbria University have…

Making COTS Rad-Hard for Space
The rapid expansion of satellite constellations has created a trillion-dollar space data challenge driven by unprecedented data volumes, limited downlink capacity, and increasing demands for real-time decision-making. Modern satellites routinely generate terabytes of data per day, yet traditional architectures rely on transmitting raw data to Earth for processing. This approach is constrained by expensive and…
