Title (EN) MICROSATELLITE SYSTEM FOR HIGH-VOLUME ORBITAL TELEMETRY
(FR) SYSTEME MICROSATELLITAIRE POUR TELEMESURES ORBITALES A GRANDE ECHELLE
Abstract:
(EN) Detailed mapping of the magnetosphere is made possible by deploying hundreds of attitude-impervious microsatellites, in the form of small corner reflectors with piezoelectric mirror surfaces (10), from a single mother satellite at spacings of as little as 1 km in equatorial and elliptical orbits. The microsatellites carry magnetosensors whose output is transmitted to a ground station by modulating the reflection of a laser beam transmitted to the microsatellite by the ground station. Various refinements of the laser data link are also disclosed.
(FR) Une cartographie détaillée de la magnétosphère est rendue possible par le déploiement, à partir d'un seul satellite-mère, de centaines de microsatellites indépendants de l'attitude, sous la forme de petits réflecteurs polyédriques à surfaces miroir piézo-électriques, séparés d'à peine 1 km sur des orbites équatoriales et elliptiques. Ces microsatellites transportent des magnéto-capteurs dont les données de sortie sont envoyées à une station terrienne par modulation de la réflexion du faisceau laser émis par la station terrienne vers le microsatellite. L'invention concerne également diverses techniques de raffinement des liaisons de données laser.
