针对直升机载导弹传递对准精度评估的实际应用需求,提出一种基于双主惯导的传递对准精度评估方法。在双主惯导之间安装误差可测定的前提下,通过对参考主惯导与弹载子惯导之间的安装误差进行离线估计,实现机载主惯导与弹载子惯导之间安装误差的定量评估。设计了相应的试验方案进行验证,结果表明,该方法合理可行,具有良好的工程借鉴意义。

Aiming at the actual engineering application requirements of the transfer alignment accuracy evaluation of helicopter-borne missiles, a transfer alignment accuracy evaluation method based on dual master inertial navigation was proposed. On the premise that the installation error between the two master inertial navigation systems is measurable, the quantitative evaluation of the installation error between the main inertial guide and the projectile inertial guide is realized by estimating the installation error between the reference master inertial guide and the projectile inertial guide. On this basis, the corresponding test scheme is designed and the method is verified, the results show that the method is reasonable and feasible, and has good engineering reference significance.
