... The described algorithm is suitable for measurements of complex images of stars. ... a) the zero-based number of stars in the complex (multicentric) image, . b) set of preliminary coordinates - x i , y i , for all stars, index i is number of a star, . ... i - index of a star in the complex image; . ... These parameters are calculated by a nonlinear method of a least squares.The main output parameters of this algorithm are x i , y i ; where the index i is number of a star in the multicentric image. ...

... The author attempts to approach the problem from the positions of systems analysis with account for the ideological grounds and history of space activities in Russia and abroad, comparing its current interpretation with the initial goals posed by leading theoreticians and practitioners who stood at the cradle of the space exploration era. ... The space systems recognized in Russia as priority projects are largely developed with violations of the systems approach principles. ...
