Fast estimation of aircraft docking attitude with reference to wave structure
Correctly and quickly measuring the attitude of aircraft is an important prerequisite for achieving precise docking missions for manned spacecraft.Traditional attitude measurement requires splicing three attitude parameters.This paper proposes an improved optimization algorithm that is applied to attitude measurement with electromagnetic wave structure vectors as reference,achieving synchronous,overall,and rapid measurement of attitude parameters.Firstly,a guidance vector is established based on the changing relationship between multiple electromagnetic vector sensors and received signals,the attitude rotation in the form of an exponential function in the guidance vector is expanded by Taylor approximation.Then an equal-step traversal algorithm combined with Newton method is used to quickly search the spectral peak of the space spectral function of multiple navigation signals,and the attitude measurement of the aircraft is completed.Simulation results show that the attitude measurement accuracy of this method is high and the error can be controlled at about 0.01°,which improves the efficiency of attitude measurement.This method also has good anti-interference ability and has good application value.
