Title (EN) METHOD FOR PLANNING THE ACQUISITION OF IMAGES OF AREAS OF THE EARTH BY A SPACECRAFT
(FR) PROCÉDÉ DE PLANIFICATION D'ACQUISITION D'IMAGES DE ZONES TERRESTRES PAR UN ENGIN SPATIAL
Abstract:
(EN) The invention concerns a method for planning the acquisition of images of areas Z1,...,ZN of the Earth, by a spacecraft on a mission around the Earth, each area Zi of the Earth being associated with a request Ri such that a visual accessibility time interval Ti corresponds to said area Zi. Moreover, the method comprises the steps of: - determining, for each interval Ti, discrete acquisition opportunities for acquiring area Zi such that a start date, a period of execution, a local kinematic constraint and a weight is associated with each of said discrete acquisition opportunities, - grouping together the discrete acquisition opportunities for acquiring areas Zi into a set D, - categorising the discrete acquisition opportunities Di of the set D by ascending start date, - assessing the kinematic compatibility between said discrete acquisition opportunities of set D, - determining an optimal sequence of discrete acquisition opportunities having a maximum weight, and being kinematically compatible.
(FR) L'invention concerne un procédé de planification d'acquisition d'images de zones terrestres Z1,...,ZN, par un engin spatial en mission autour de la Terre, chaque zone terrestre Zi étant associée à une requête Ri de sorte qu'à ladite zone Zi correspond un intervalle temporel d'accessibilité visuelle Ti. En outre, le procédé comporte les étapes de : - détermination pour chaque intervalle Ti d'opportunités d'acquisition discrètes de la zone Zi de sorte qu'à chaque dite opportunité d'acquisition discrète sont associées une date de début, une durée d'exécution, une contrainte locale cinématique ainsi qu'un poids, - regroupement des opportunités d'acquisition discrètes des zones Zi dans un ensemble D, - classement des opportunités d'acquisition discrètes Di de l'ensemble D par date de début croissante, - évaluation de compatibilité cinématique entre lesdites opportunités d'acquisition discrètes de l'ensemble D, - détermination d'une séquence optimale d'opportunités d'acquisition discrètes ayant un poids maximal, et compatible cinématiquement.
