摘　　要：通用椭球概率误差包括3个方向上的误差相关与不相关两种情况,相关系数值为0,即不相关,不相关是相关的特例。文章主要论述通用椭球概率误差计算模型、方法及软件界面设计,讨论了软件输入参数及软件输出的取值范围。三维随机变量(x,y,z)的正态分布密度函数是计算椭球概率误差的根本,该函数的表达式公开资料上没有,文章可能是首次呈现。该软件的输出自带验证功能,软件使用者可以知道输出结果正确与否,这是本软件的一个特点。文中软件经过数据输入运行验证,输出结果正确。General ellipsoid spherical probability error includes two instances of error correlation and irrelevance on three directions.Correlation coefficient is zero,namely irrelevance.Irrelevance is a special example of correlation.This paper mainly discusses the computational model,method and the software interface design for general ellipsoid spherical probability error.It discusses the parameter scope of software input and software output.The normal distribution density function for 3D random variable is root that computes ellipsoid spherical error probability.The author has not found the expression of the function in open information.This paper may be the first one to present the expression.The software output has the function of self-validation.The software has a characteristic that the user can know whether the output result is right or not.The software is validated by running the input data,and the output result is right.
