Signal Quality Monitoring: Test Results

Abstract:	This paper presents the background on signal quality monitoring (SQM) and the importance of such monitoring of the Global Positioning System signal for both ground-based and space-based augmentation systems (GBAS and SBAS). The metrics used to determine the quality of the signal are based on C/A correlation function measurements. In order to establish alarm thresholds for such a monitor, statistics must be collected to determine the nominal variation that can be expected in the measurements. Included in this paper are the initial statistics that can be utilized for monitor development, a description of the hardware used to gather the data, and C/A code specifics which must be taken into account in the development of a signal quality monitor.
