An enlarged algorithm for solving the planning problem for different types of spacecraft is described. The result of the enlarged algorithm is sought in the form of a set of reference plans for groups of similar spacecraft, thinned out by removing some of the conflicting operations of resetting the sensing data. The characteristics of the developed plans largely depend on the methodology used to account for the impact of cloud cover. The possibility of implementing a methodology based on the use of files of current weather forecasts of hydrometeorological centers downloaded from the Internet in the form of a special application is investigated. The created application is being tested on the real data of the hydrometeorological center downloaded from the American server, which covers a large region, including the European part of Eurasia and part of Africa. An application that simulates the distribution of points within a region estimates the number of points covered by weak cloud cover (20% or less). Based on the results of the simulation, it was found that the proportion of points available for shooting lies in the range from about a quarter to a third. Based on the obtained quantitative estimates, it is concluded that taking into account the influence of cloud cover radically changes the reference plans calculated taking into account only illumination, and affects the structure of the enlarged planning algorithm.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Статья посвящена актуальной задаче планирования работы группы разнотипных космических аппаратов дистанционного зондирования Земли. Описывается укрупненный алгоритм решения задачи планирования для разнотипных КА. Результат укрупненного алгоритма ищется в виде совокупности опорных планов для групп однотипных КА, прореженной за счет удаления части конфликтующих операций сброса данных зондирования. Характеристики разрабатываемых планов в значительной мере зависят от используемой методики учета влияния облачности. Исследуется возможность реализации методики, основанной на применении скачанных из Интернета файлов текущих метеопрогнозов гидрометцентров, в виде специального приложения. Проводится проверка созданного приложения на скачанных с американского сервера реальных данных гидрометцентра, которые охватывают большой регион, включающий европейскую часть Евразии и часть Африки. С помощью приложения, моделирующего распределение точек внутри региона, оценивается число точек, накрытых слабой облачностью (20% или менее). По результатам моделирования установлено, что доля доступных для съемки точек лежит в интервале от примерно четверти до трети. На основе полученных количественных оценок делается вывод о том, что учет влияния облачности коренным образом меняет опорные планы, рассчитанные с учетом только освещенности, и влияет на структуру укрупненного алгоритма планирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>space survey planning</kwd><kwd>assessing the impact of cloud cover</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>космические аппараты дистанционного зондирования Земли</kwd><kwd>планирование космосъемки</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Emelyanov AA, Malyshev VV, Smolyaninov YuA, Starkov AV.
