摘要
Abstract
Traditional methods of Tri-frequency cycle slip detection are based on the difference of epochs,which requires that the combination do not contain geometric distance. And that causes a strong constraint in the combination.When the polynomial fitting applies to the Tri-frequency cycle slip detection,the constraint is relieved.In static case,this novel applies the polynomial to Tri-frequency cycle slip,and defines ionosphere amplification fac-tor、clock bias amplification factor and noise amplification.The results shows that this meth-od can detect at least 1 slip.关键词
