Without any external source and not reducing independency, if damping technology is adopted in the system, it can weak period vibration error and navigation positioning error caused by gyro random drift, improving navigation system precision effectively. 采用阻尼技术能在不引入外部信息源、不降低系统自主性的前提下,实现惯导系统的周期振荡误差以及陀螺随机漂移激励的导航定位误差的衰减,有效的提高惯导系统精度。
This paper summarized the method of the random drift testing and data recording system of the hydrodynamic gas bearing free rotor gyro. In addition, the result of the random drift testing was brought to pass statistical analysis and processing. 本文总结了动压气浮自由转子陀螺仪随机漂移测试方法和数据记录系统,对测试结果进行了概率统计分析和处理。
