As the SPS signals travel from the GPS satellites to the GPS receivers the SPS signals travel through the ionosphere which encircles the earth. The ionosphere acts as a dispersive medium and refracts the SPS signals as they travel through the ionosphere. As a result, the SPS signals do not appear to travel at the speed of light, which is assumed in the calculation of the position of the GPS receiver. The ionospheric induced delay in the reception of the SPS signals limits the accuracy of the determination of the position of the GPS receiver and is the largest location dependent error source in the
