一、序 言 捷联式惯性控制系统的陀螺敏感元件是直接安装在飞行器壳体上。因此,飞行器的角运动将传给陀螺本身,并引起一系列误差的出现。由于在作为角速度传感器应用于捷联式系统中的液浮陀螺中存在有反馈回路（它是建立相对于进动轴的恢复力矩）,以及要进行座标转换的必要性,将导至另外误差的出现。在高精度的捷联式惯性系统设计时,需要很仔细地研究所有这些误差。
I. Preface The gyroscopic sensing element of the strapdown inertial control system is mounted directly on the aircraft shell. Therefore, the angular movement of the aircraft will be transmitted to the gyroscope itself and cause a series of errors to appear. Since there is a feedback loop in the liquid-floated gyroscope used in the strapdown system as an angular velocity sensor, which establishes a recovery torque relative to the precession axis, and the necessity of coordinate transformation, a further error The emergence of. In the design of high-precision strapdown inertial systems, all these errors need to be carefully studied.
