Abstract:	The GALILEO Satellite Navigation System aims for rather demanding goals w.r.t. accuracy, integrity, continuity and availability. This results in stringent requirements on GALILEO ‘Signal Quality’, which can be grouped into four main domains: Functionality and service provision including Integrity and Commercial Service, Signal timing and clock stability aspects, navigation message accuracy and timeliness, and finally signal level quality comprising signal power, modulation and correlation accuracy of each emitted signal-in-space. All modulation and correlation related parameters of this last group are covered by Offline SIS Quality Analysis (OASIS), which can be understood as an extended set of high precision receiver processing of signal samples. This analysis tool is subject of this paper.
