摘要
惯性/重力匹配组合导航系统的导航精度与重力场有很大关系.论文从局部可观测性出发,分析了重力场对该组合导航系统定位精度的影响,认为惯性/重力匹配组合导航系统的位置是局部可观测的,且定位精度受重力场的诸多综合因素的影响.
The position precision of Inertial/Gravity match integrated navigation system was greatly influenced by gravity field. The paper analyzed the influence of gravity field＇s roughness to the integrated navigation system by local observability, then deduced that the position of this integrated navigation system was locally observable and position error could be bounded to some degree which confined by compositive facts of gravity field.
