attitude estimation meaning in English
姿态估计
Examples
- In general , the estimation accuracy not only lies on the performance of the hardware of the measurement , but also the attitude estimation algorithm
姿态确定的精度不仅取决于姿态测量系统硬件配置的性能与精度,还与所采用的姿态确定算法密切相关。 - The main contents of this dissertation consist of the following parts : an improved unscented kalman filter using spherical simplex unscented transformation ( sukf ) is derived in an attempt to solve the attitude estimation problem with the biased gyro or not from the vector observations
主要完成了以下几方面的工作:针对有陀螺和无陀螺两种模式,提出了一种基于简化球形分布sigma点ut变换的改进型ukf滤波( sukf )的卫星姿态估计算法。 - In this dissertation , the nonlinear filter methods are deeply studied on theory and application for the attitude estimation from vector observations of the three - axis stabilized satellite attitude measurement system . furthermore , for the shortages in extended kalman filter , several improved schemes are presented
本文针对基于矢量观测的三轴稳定对地定向卫星的姿态确定问题,从理论和应用两个方面对卫星姿态确定的非线性滤波技术作了深入和细致的研究。 - The high precision flight attitude of spacecraft has been mainly received through star sensor . the priciple is that at first the star acts as reference and the stars image has been captured by star sensor , then stars image identification and attitude estimation have been done , at last the flight attitude of spacecraft has been received
航天器的高精度姿态确定主要是通过星敏感器来完成的，首先是以恒星为参照物，利用星敏感器得到星图，然后进行星图图像处理、星图识别和姿态估算等一系列计算，达到确定出航天器的飞行姿态的目的，而星图处理是星敏感器处理的基础。 - In order to improve the performance of ekf and ukf , the square soot unscented kalman filter ( sr - ukf ) with multiplicative noise is firstly investigated . considering the satellite nonlinear model , the sr - ukf attitude estimator is derived for gyroless satellite attitude estimation to render the state covariance with positive semi - definiteness and exceptional estimation accuracy
对于姿态估计,采用了rao - blackwellization技术将卫星模型状态向量中的线性状态部分(陀螺偏差)和非线性状态部分(卫星姿态)分开处理,线性部分状态可以由卡尔曼滤波( kf )估计得到,非线性部
