Determining the local vertical line direction for CubeSat class nano-satellite by the Earth images analysis
The study deals with applying video images to determine the local vertical line of a nanosatellite. In the research we develop algorithms for solving the task and present the basic formula, the result of numerical experiment. Finally, we make the conclusions concerning the systems application.
