Abstract:	There are a number of different error sources which corrupt the pseudorange measurements of navigation receivers. Multipath and noise remain difficult to erase and represent the most critical problem for several Global Navigation Satellite System (GNSS) receiver applications. However, for high performance applications such as GPS-based aircraft navigation and landing system, even smaller error contribution must be considered in the error budgets. For example, the minor differences between the signals broadcasted from the GPS satellites have to be detected and quantified. This paper describes an experiment performed in Green Bank, West Virginia, where a 110 meter high gain antenna was used to receive the signal broadcasted by GNSS satellites. The paper will present the most important results of the analysis toolset specifically developed to process the collected data. Diagrams and measurements will be shown, highlighting the differences between the signals from each of the satellites.
