摘　　要：随着载波相位观测技术与网络通讯技术的发展与成熟,对于区域内GPS改正数模型化并通过网络传播于用户的研究亦已取得相当的成果。对偏导数算法(PDA)和线性内插算法(LIA)两种改正数模型化方法进行探讨,并说明两种方法的优缺与应用范围。With great improvements had been made and applied to position with carrier phase and internet broadcast, searchers have done more further to model the corrections of GPS network, which been sent to users. Here we expound two approaches to GPS corrections model by Partial Derivative Algorithm （PDA） and Linear Interpolation Algorithm（LIA）, then probe their advantages and disadvantages.
