A new type of inertial navigation system combining customary platform type with strap-down one is put forward. In this system the azimuth rate platform without azimuth stabilized loop, coordinate-resolver and azimuth syn chronzer is adopted. The azimuth angles of platform and vehicle will be obtained by an integrator from azimuth rate signals measured by an azimuth gyroscope supported on a horizontal gimbal. This type of inertial navigation system is suitable for vehicles without large-pitching maneuver, such as transports, aerodynamic and ballistic missiles.Operational principles of the azimuth rate platform, mechanization equations, distinguishing features of initial alignment, and calibration and compensation for drifts of gyroscopes are discussed in this paper. Error propagation characteristics caused by various error sources for navigation positioning, velocity and attitude are simulated on a digital computer. Simplicity in platform structure, small volume and weight, high reliability, possibility of calibration and compensation for drifts of the azimuth gyroscope are the distinctive advantages of this inertial navigation system.Moreover, by using a specific optical system referring to given azimuth angles of land marks and geographical latitudes, it is possible to accomplish not only fast alignment, but also calibration and compensation of horizontal gyroscope.

本文提出一种把平台式和捷联式惯导系统结合在一起的新的惯性导航系统。在该系统中使用的速率方位平台没有方位稳定回路、方位坐标分解器及同步器。平台和运载器的方位角是根据由水平环架支承的方位速率陀螺讯号借助积分运算得到的。这种惯导系统适用于运输机、飞航式及弹道式导弹等不作大角度俯仰机动的运载器。文中叙述了方位速率平台的工作原理、力学编排方程、初始对准的特点以及陀螺漂移的标定和补偿;同时对各主要误差源所引起的姿态、速度和导航定位误差的传播特性进行了模拟计算。在结论中指出:平台的结构简单、体积小、重量轻、可靠性好、可对方位陀螺的漂移进行标定和补偿是其独特优点。另外,如果利用专门的光学系统,配合已知地标的方位角和纬度,不仅能够实现快速对准,而且还可进行水平陀螺的标定和补偿。

The initial alignment is a key link for the output precision of strapdown inertial system and gyro drift is one of the main causes producing alignment error of the system. In view of the problem, a multistage Kalman filtering method is proposed in this paper, on the basis of analysing the error of strapdown system and combining the characteristics of Kalman filter, which combines the random constant drift calibration of gyro with the initial alignment technique.

在捷联惯性系统中,初始对准是影响系统输出精度的最重要环节,陀螺漂移是引起对准误差的主要原因。本文在对捷联系统误差进行分析的基础上,结合卡尔曼滤波器的滤波特性,提出一种把陀螺随机常值漂移标定与初始对准进行多级组合的卡尔曼滤波方法。

A new fading filtering algorithm has been developed based on the property of Kalman filter that the sequence of residuals is uncorrelated when the optimal gain is used.The algorithm adjusts the fading factor adaptively using measured outputs so as to improve the optimality and convergency of the Kalman filter when there exist model errors and/or when the plant is affected by unmeasurable external disturbances .The proposed algorithm has been applied to calibrating of gyro random constant drift and behaves satisfactorily...

本文依据卡尔曼滤波器在使用最佳增益时,其余差序列互不相关的性质,开发了一种新的渐消滤波算法。该算法根据对象输出,在线自适应地调整遗忘因子,从而使滤波器在对象模型存在误差或对象受到外扰时,仍收敛并保持最佳性。该算法应用于陀螺随机常值漂移的标定,取得较好效果
