| 摘 要： | 系泊状态下,用Butterworth低通滤波器解决舰载RLG PINS初始对准中杆臂效应问题时,对准的精度受安装误差、杆臂长度和舰船摇摆等因素的影响。通过仿真分析,认为Butterworth低通滤波器适于解决风浪干扰下的舰载平台系统初始对准中的杆臂效应问题,且安装误差、安装位置是影响对准精度的主要因素,提高系统标定精度,并尽量使系统安装在船体对称面内,可以提高对准精度。

| Abstract: | The initial alignment accuracy is affected by installation error,arm length and ship rocking when solving the arm effect error by Butterworth Low Pass Filter for carrier-borne RLG PINS in moorage.Simulation calculations are given to show that is effective to solve arm effect by Butterworth Low Pass Filter, and the installation error and the installation position are the main factors which effect the alignment accuracy,so it should be improve the calibration accuracy and install the RLG PINS at the barycente... |
