摘要:
针对舰载武器传递对准的精度评估方法对载体线运动特性要求高的问题,结合舰船的机动能力,提出了一种舰船姿态辅助差分GPS(DGPS)的传递对准精度评估方法.该方法以舰船主惯导提供的姿态信息来辅助DGPS提供的速度、位置信息进行评估.以准惯性坐标系为子惯导导航坐标系,推导评估系统状态方程,并建立精度评估的滤波方程;以舰载主惯导和GPS输出为观测量,建立基于“姿态+速度+位置”观测量的精度评估观测方程;设计卡尔曼固定区间平滑算法分别对引入舰船水平姿态信息及引入“水平+方位”姿态信息2种方法进行仿真,并与传统的精度评估方法进行了对比分析.仿真结果表明,该方法借助舰船的摇摆运动即可完成传递对准的精度评估,降低了精度评估对舰船机动强度的要求,是一种有效实用的精度评估方法.
