title = "Analysis and simulations of GDOP in the location of GPS",
abstract = "In this paper, the GDOP (Geometric Dilution of Precision) in the location of GPS (Global Positioning System) is studied from three aspects: First, a new algorithm of GDOP is obtained by matrix factorization. The validity of the new algorithm is proved by simulation comparing with the old method. Second, the measurement accuracy of stand alone positioning with weight GDOP matrix becomes better: the 2drm decrease by 0.096m. But, measurement accuracy of DGPS (Difference GPS) with weight GDOP matrix changes little: the 2drm only decrease by 0.012m. By analyzing the principle of the DGPS, the conclusion is explained. Third, using a new parameter GDOPi to evaluate each satellite, and the method could improve the positioning accuracy of DGPS and also will be helpful the surveillance of the satellite availability.",
