An improved UKF method is proposed and applied to the nonlinear initial alignment of SINS on the stationary base. Simulation results illustrate that the given method has a better performance in the estimation of the azimuth error than the EKF, traditional UKF and scaled SSUKF does. Based on the dynamic error equations of SINS, the mathematics model of the IMU/GPS integrated navigation system is derived for Kalman filtering.

此外，论文还分析和研究了捷联惯性导航系统的力学方程编排和惯性仪表的误差，建立了IMU/GPS组合导航系统的状态方程和量测方程，设计和开发了用于机载SAR运动补偿的组合导航实验系统，并对设计的组合系统进行了大量的静态实验和车载实验。

Therefore, we can choose a little worse east and north gyros to cut down the cost of the navigation system.Thirdly, SINS/OD integrated system fails to diminish the error of azimuth angle, this paper introduces the regional positioning system based on Pseudo-Satellite as a member of the integrated system to diminish the error of azimuth angle in the moving state, and further improve the precision of positioning and orientation.

仿真结果表明，天向陀螺漂移和初始方位误差角对系统的定位精度影响较大；而东向和北向陀螺漂移对系统定位精度的影响较小，因此系统中就可以适当放宽对东向和北向陀螺精度的要求，这样就可以适当降低系统的成本。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
