Abstract

Global Positioning Systems (GPS) refers to satellite-based radio-positioning systems and time-transfer systems that provide three-dimensional course, position, and time information to suitably equipped users. At present, GPS system is world-wide used for positioning and navigation, attracting great attention from the scientific, professional and social community.GPS satellites are orbiting Earth at altitudes of 20.200 km and the GPS signal is mostly affected by the atmospheric effects. The scope of this paper is to investigate the performance impact of the atmospheric correction models in the overall positioning accuracy. Real GPS measurements were gathered using a single frequency receiver and post–processed by our proposed innovative adaptive LMS algorithm. We integrated Klobuchar and Hopfield correction models enabling a considerable reduction of the vertical error.
