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…
