摘要： 传统的飞行器射前电参数判读对于惯性自对准误差控制而言并不可靠，为保证飞行器在进入飞行导航前进行惯性自对准所得精度适用，梳理研究了几种在线验证方法，包括常规的基于光学的直接瞄准方法、创新提出的光学与过渡装置结合的间接方法及基于不同路径数学估计修正方法。对直接光学瞄准方法的精度影响逻辑进行了分析，介绍了新的验证方法的原理思路；梳理了各方法的误差因素与应用特点。通过理论分析与应用实践，表明了这几种方法的适用性。

Abstract: The traditional control method of aerocraft inertial self-alignment precision through examining electrical parameters is unreliable.To ensure the precision applicability of aerocraft inertial self-alignment executed before flight navigation,several online validating methods are analyzed and researched,including the conventional direct optical sighting method,the methods proposed innovatively of indirect optical sighting combined with transitive device,and the mathematic estimate correction method based on different calculating paths.The errors [JP3]effect process of direct optical sighting method is analyzed,and the new conceptions of validation methods are descripted.Meanwhile,the error elements and application specialties of these methods are sorted out.These methods’ feasibilities are verified by theoretical analyses and application practices.

Key words: Aerocraft, Self-alignment, Precision
