Abstract :
GPS (global positioning system) is a 3D positioning system using the signal of satellites and can be applied in many situations. GPS has positioning error due to various factors. We paid attention to a method so called DGPS (differential GPS) that requires a reference station to measure. For precise positioning by DGPS, we used weighting coefficients of elevation angle of satellites in the calculation and corrected bias error. We have succeeded to improve the accuracy in the measurement of long baseline DGPS.
