The paper presents a mathematical model of DGPS correction and their weights in post processing positioning when we use two reference stations at the same time. The traditional DGPS is based on one reference/base station. It has been shown that the accuracy of thet positioning is about 1-2 meters in dependence of a number of satellites and value of PDOP (Position Dilution of Precision). The paper shows that when we use, simultaneously, two reference stations we can analyze distribution of pseudorange corrections over time and model them. Two refernce stations used in DGPS positioning give redunndant observations and allow to estimate more realistic accuracy of positioning.
