On-line integrated correction of attitude and heading for single-axis rotary SINS
摘要
Abstract
In order to improve the positioning accuracy of the single-axis rotary strapdown inertial navigation system(SINS)in the underwater environment,a processing for on-line integrated correc-tion of the attitude and the heading angle of the inertial navigation system is presented,and a second initial alignment method for the rotary SINS based on velocity information is also proposed.By utili-zing velocity information and Kalman filtering technology,the attitude and heading errors are opti-mally estimated and the systematic observability is improved by periodically rotating the inertial measurement unit.The results of computer simulation and turntable verification experiments show that the positioning accuracy of the following pure inertial mode can be obviously improved by the second initial alignment.In the simulation experiment,the positioning error reduces from 4.52 to 2.19 n mile,and in the turntable experiment,the positioning error reduces from 4.28 to 2.06 n mile.关键词
