DEVICE AND METHOD FOR SIMULATING THE ESTIMATION OF A LAG IN PRODUCING SATELLITE IMAGES OF THE EARTH

摘要

A method for simulating the estimation of a time to acquire satellite images associated with at least one predetermined area of the Earth, by at least one Earth observation satellite having an optical imaging system, the predetermined area being previously divided into a grid of cells, the acquisition being scheduled to be triggered starting on an analysis start date is disclosed having the steps of: (a) conducting an inventory of the cells planned to be overflown by the satellite on a current iteration date, on the basis of the orbital characteristics of the satellite on the current iteration date, thus obtaining candidate cells, (b) identifying among the candidate cells, on the basis of a mission plan of the satellite, those cells for which acquisition of at least one satellite image is scheduled, thus obtaining scheduled cells, (c) obtaining at least a first cloudiness value for each of the scheduled cells, (d) identifying, among the scheduled cells, those for which the first associated cloudiness value is above a predetermined validation threshold value, thus obtaining validated cells.
