METHOD FOR AVOIDING A FORBIDDEN AREA BY A SATELLITE

摘要

The invention relates to a method for calculating attitude maneuvers of a system, from a starting point (A) to a point of arrival (B), under constraints of pointing directions to avoid which correspond to at least a forbidden zone towards which the machine points according to a pointing axis by following a so-called unstressed initial trajectory going from the point of departure (A) to the point of arrival (B), the method comprising steps ofE1) determining at least one so-called avoidance point, such as an avoidance trajectory of the pointing axis deviating from the initial trajectory (A-B) through the avoid point to avoid the forbidden zone;E5) determination of satellite maneuvers allowing the pointing axis to follow the avoidance path,E6) selection, among the maneuvers determined, according to the direction of circumvention of the prohibited zone or zones, the best sequence of maneuvers to achieve.
