Analysis and Mitigation of Tropospheric Error Effect on GPS Positioning Using Real GPS Data

The GPS (Global Positioning System) is used for navigation and positioning purposes by a diverse set of users. The navigation solution provided by a commercial GPS receiver is subject to errors contributed by various sources. These sources of errors in GPS navigation (e.g. satellite clock, receiver clock, atmospheric, multipath errors, etc.) induce biases in the measurement of pseudo range and degrade system accuracy. In the current research endeavor the atmospheric and troposphere error sources and its impact on GPS position accuracy is critically analyzed. In this regard, a tropospheric error correction model is simulated on real captured GPS data and results are analyzed.
