摘　　要：为实现某型导弹非全姿态惯性平台射前自标定,提出了一种非全姿态惯性平台射前速率标定方案,在确定平台误差模型的基础上,充分利用平台自身的特点,通过增加小型测控设备,在平台转动过程中,实现开环测试与闭环测试同步进行,使平台转动一次即可激励和标定出误差模型中的所有系数,大大缩短了测试时间,很好地解决了射前标定精确性与快速性的矛盾。分析表明,该方案具有实际工程应用价值。For realizing the error calibration of the non-full gesture inertial platform before launch, the speed calibration methods for the platform are presented. The error models are analyzed and fixed on. The characters of the inertial platform are taken and a small test facility is introduced . When the platform rotating, tests of open loop and closed loop go along in-phase. The error coefficients are powered sufficiently and separated after the once rotation of platform. The time of test is less than before. The contradiction of precision and celerity are solved. Precision analysis shows that this project possesses actual value of application,
