Abstract
The mathematical expressions, specifying the estimation of the capabilities of remote sensing satellites with opto-electronic imaging equipment for observing the Earth’s surface with the necessary (predetermined) spatial resolution of the space imaging materials when deflecting the optical axis of on-board information complex, are obtained and substantiated in the article. The validity of the obtained expressions is proved by comparing the results of the solution of the direct and inverse problems of determining the spatial resolution of the space imaging materials when the optical axis of the on-board information complex of remote sensing satellites is deflected. Taking into account the deterioration of spatial resolution depending on the angle of deviation of the on-board information system of the satellites and the curvature of the Earth provides increasing the accuracy in determining the field of regard of satellites when modeling the state and changes in the space situation, as well as assessing their surface capabilities for space imaging. The capabilities of remote sensing satellites with opto-electronic equipment have been evaluated and it has been proved that the space imagery they receive cannot be applied to detect and identify (to the kind, class, type) objects of observation within the entire field of regard of imaging equipment, provided that the claimed spatial resolution of the space imaging materials. Prospects for further research are the refinement solution of practical problems in planning the use of on-board resource of remote sensing satellites, the improvement of algorithms for taking into account the possible observation of domestic territory (objects) with the help of foreign spacecraft’s and improving the methods of estimation of the remote sensing satellites with radar equipment.
