摘要
Abstract
Grid ionosphere vertical correction error（GIVE） is the estimation of grid ionosphere vertical error.It will influence the system＇s integrity when the estimation is too big,otherwise it will influence the system＇s usability,commonly it expressed by the overbound on some probability.This paper presents a improved arithmetic of grid ionosphere vertical correction error.In the condition of assuring the risk probability this arithmetic make the estimation more approach the true value,and advance the system＇s usability.The practical analysis indicates this arithmetic useful and effective.关键词
