| 摘 要： | 舰船停泊在港口或者在海上抛锚时,由于受到海浪的冲击而发生摇摆,这对从舰上起飞的飞机激光惯导对准提出了新的课题.本文利用基于惯性系重力加速度的粗对准算法获得了较高精度的初始姿态和航向,在此基础上利用卡尔曼滤波对姿态和航向残差进行估计和修正,实现了动基座条件下高精度对准.

| Abstract: | Ship rocks with large amplitudes caused by waves when anchoring on sea or mooring at haven,which brings forward a new subject to Aircraft Laser Gyro Inertial Navigation System taking off from ships.This paper gains higher precise attitude and heading using a kind of coarse alignment scheme on the gravity in inertial space,and on which higher precise aligmnent on moving base is realized utilizing KF to estimate and modify the errors of attitude and heading. |
