Abstract
A method and apparatus to perform the observation and imaging from a space vehicle by scanning of a celestial body with reference to a scanning axis, forming successively two signals corresponding to the scanning in a given directional series of a line or band including ground area, detecting in each of these signals a characteristic transition representative of a given characteristic point of this line or band of ground, reading the relative position of these transitions in these signals, and determining an angular velocity of the space vehicle from any divergence between these relative positions while taking into account the time interval separating the instants where each of these transitions appeared in the aforementioned formed signals.
