| 摘 要： | 研究了组合导航系统中杆臂效应引起的干扰比力问题。文中给出了几种飞行状态下由杆臂效应引起的导航误差。分析表明 ,当飞机作机动飞行时 ,杆臂效应引起的干扰比力是主要的误差源之一 ,并且由干扰比力产生的导航误差随时间快速积累。因此 ,在组合导航系统中必需考虑在线的补偿方法 ,以便补偿由杆臂效应引起的导航误差。

| Abstract: | Disturbance specific force caused by the lever arm effects in integration navigation system is investigated. Navigation errors caused by the lever arm effects have been demonstrated under three flight scenarios of the aircraft. Analytical results show that disturbance specific force resulted from lever arm effects may become one of the major error sources while an aircraft undertakes the maneuvers, and navigation errors caused by the lever arm effects accumulate rapidly with time. Therefore, a compensation method must be taken into account to eliminate the disturbance specific force caused by the lever arm effects in integration navigation system. |
