Abstract :
GPS (Global Positioning System) is 3D positioning system using the signal of satellites, and it is used in va rious situations. The arrangement and the number of GPS satellites influence measurement accuracy. However, error f actor by ionosphere delay exists in GPS measurement. We aim at the improvement of the measurement accura cy by this correction of ionosphere delay through experiments and simulations.
