Comparison of the Stochastic Models for Double-Differenced GPS Measurements

Autor: Dudy Darmawan, Fumiaki Kimata

Publikováno v: ITB Journal of Engineering Science, Vol 36, Iss 2, Pp 95-108 (2004)

Double-differenced GPS carrier phase measurements are commonly used in GPS precise positioning applications and processed with algorithms based on the least-squares (LS) principle. In order to apply the LS principle, one needs to define properly both
