The paper deals with processing video data obtained by composite (multimatrix) optoelectronic converters used in purpose designed equipment of observation space vehicles. It is shown that the video data obtained in the areas of intersection of fields of view of two adjacent photosensitive matrices can be beneficially used to solve a number of tasks: assessing the quality of performance of spacecraft motion control system on the survey routes, specifying the parameters of image blur, assessing the deviations of the geometrical arrangement of photosensitive matrixes from the design parameters and some other tasks.
