| 摘 要： | 某型平台惯导系统采用方位旋转调制技术,通过对台体匀速转动的控制调制陀螺的漂移。台体的转速不是固定值,是随惯导系统所在地区而改变的,且台体转速异常必伴随方位陀螺故障。为了正确判断台体转速的理论是否正常,文章推导了转速的理论计算公式,不同地区惯导系统的实测数据表明实测值与理论计算值一致,验证了转速计算公式的正确性,为监控方位陀螺状态提供了技术途径。

| Abstract: | Acentain type of inertial navigation system used revolution-modulation technology. The gyro drift was modulated by rotation of the azimuth. The revolution rate was not a constant, it varied with location. When azimuth gyro fault emerged, the revolution rate is abnormal. In order to predict of rate fault, the rate calculation formula was derived. The experiment results verified the correctness of the formula, which provide techniqued support for azimuth gyro condition estimate |
