Aerospace Instrument-Making Annotation << Back Information spacecrafts purpose opportunity estimation Yu.S. Manuylov, E.A. Novikov, S.V. Zinov’ev, V.V. Yashchenko The problem of purpose productivity increase of surveillance information spacecrafts is considered. Dependence of purpose effect at service of the multielement ground group targets from maneuverable opportunities provided by an angular movement control system of spacecraft is proved. The estimation technique of purpose opportunities based on the analytical decision of operative spatial angular maneuvering problem and combinatory problem of optimum targets distribution is offered.
