Star tracker matrix ccd, a process of detection, and an application to the resetting of a spacecraft.

摘要

For the analysis of the image of a faintly luminous objects in a rapid movement, the sighting device (1) receives information from coming from an inertial unit (18). It also has a cross section of a digital memory (17) of a window which contains the image of the object of the light. The tiles contained in windows realigned in succession, on the ccd matrix (3) are summed progressively and stored in a cross section of a digital memory (17) of the window. The sighting device (1) is also provided with calculation means (12) in order to determine the position of the image of the object of the light beam on the matrix (3) by calculation of the centres of gravity and the vector sum of these centres of gravity. & br / application to the resetting of an artificial satellite.
