Airbus Helicopters touts U145 concept as armed ‘drone mothership’ platform
Uncrewed rotorcraft pitched at utility and ‘drone mothership’ applications. Airbus Helicopters displayed its recently-revealed U145 uncrewed rotorcraft concept at the ILA Berlin air show, highlighting two of its potential future operational applications. With its...
UAV Multi-Aircraft Collaborative Inspection Track Planning in Complex Dynamic Environments
To address the problems of state estimation bias, dynamic threat response lag, and insufficient safety margin in formation coordination caused by the mismatch between the three-dimensional continuous motion model and the discrete sampling characteristics of sensors in...
Why Orbital Data Centers Are Harder Than Silicon Valley Thinks
“Space computing, the final frontier, has arrived,” Nvidia CEO Jensen Huang declared at the Nvidia GTC conference in March. Indeed, the idea of data centers in orbit has gone from science fiction to a serious spending category. Elon...
Décollage réussi d’une fusée H3, fleuron du programme spatial japonais, avec six petits satellites à bord
Une fusée H3, fleuron du programme spatial japonais, a été lancée avec succès, vendredi 12 juin, avec six petits satellites à son bord, selon des images diffusées en direct par l’Agence d’exploration aérospatiale japonaise (JAXA). « La combustion du deuxième étage, le...
Space-Based GNSS Radio Frequency Interference Detection Evaluation Through Multi-Satellite Data Integration
Space-based GNSS reflectometry (GNSS-R) can detect terrestrial radio frequency interference (RFI) through elevated noise power in delay-Doppler map forbidden zones. This study evaluates how constellation size affects detection performance using Level 1 delay-Doppler...
