Ranging only relative navigation analysis method for double-satellite formation periodic relative motion

Abstract

The invention relates to a ranging only relative navigation analysis method for double-satellite formation periodic relative motion. The analytical autonomous relative navigation of periodic relativemotion formation double satellites can be achieved only depend on off-centroid installation of an antenna receiver and an attitude mirror image maneuvering aid in the case that satellites do not perform special orbit maneuvering or a satellite-borne data link receiving antenna is not increased. A relative orbital motion equation of the double satellites in a double-satellite formation is taken asa navigational state equation to evolve a relative orbit, a relative position and a relative speed are calculated with relative distance information before and after attitude mirror image maneuveringmeasured by a satellite-borne data link antenna receiver installed in a way deviating from a satellite centroid, and the ranging only relative navigation of the periodic relative motion formation double satellites is completed. By introducing an eccentric effect of the off-centroid installation of the antenna receiver, the observable ability of a ranging only relative navigation solution is obtained, and the relative position and speed are analyzed, solved and obtained by using the attitude mirror image maneuvering aid.

Description

technical field [0001] The invention belongs to the field of space autonomous relative navigation, and relates to a relative navigation analysis method for the relative motion of a double-star formation cycle only. Background technique [0002] With the development of space technology and the deteriorating space environment, the complexity of space missions is increasing. A large part of the tasks that can be completed by a single expensive and precise satellite in the past will be gradually replaced by distributed satellite systems due to problems such as high cost, long development cycle, poor maintainability, and limited working life. [0003] One of the important links in the work of the distributed satellite system is satellite formation flight, and high-precision relative navigation is the key premise of formation flight. The commonly used microwave radar can only be installed and used on large spacecraft such as spacecraft because of its complex system, high cost, an...
