Spaceborne power systems must operate reliably for decades with minimal maintenance. Thermoelectric generators (TEGs) are intrinsically suited to long-lived missions, but their output remains constrained by available thermal gradients and the limitations of bulk...
This paper presents a test setup for evaluating Internet of Things (IoT) nodes used in pre-launch satellite qualification, with a focus on a temperature aware power manager (PM). The PM dynamically routes energy between a battery and a supercapacitor, entering a...
Le 3 février dernier, alors que le satellite Mercury One survolait la Terre, un petit boîtier a libéré un ressort en titane d’un mouvement simple mais disruptif. Il s’agissait du JPL Additive Compliant Canister (JACC), une démonstration technologique du Jet Propulsion...
Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide-area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in...
Radio Frequency Interference (RFI) is a growing concern for Global Navigation Satellite System (GNSS) reliability. The Cyclone GNSS (CYGNSS) constellation, designed for ocean wind retrieval via GNSS reflectometry (GNSS-R), provides Delay-Doppler Maps (DDMs) with noise...
La firme israélienne Rafael entend franchir une nouvelle étape stratégique. L’entreprise ne se contente plus de produire des moteurs : elle développe désormais des plateformes satellitaires complètes, intégrant propulsion, navigation, systèmes de contrôle et...
