基于标准化残差的相关观测抗差估计模型
Robust Estimation Model for Correlated Observations Based on Standardized Residuals
【摘要】 根据观测误差与解差函数的关系,建立了山标准化残差构造的相关观测抗差估计模型。
【Abstract】 This paper builds robust estimation model for correlated obscrvations structured by standardized residuals from the relationship between the observation crrors and the function of difference solutions. By calculating and analyzing GPS network with simulative gross error. this model not only has good robustinity to both observation space and design space.but also can eliminnte the infulence that the unsuitable prior standard error of unit weight takes on the robust estimation effect.
