Abstract:	The infamous undetected failure of GP S Satellite PRN 19 instigated studies investigating the ground network detection of satellite signal anomalies and the placement of design constraints on aviation GPS receivers. These anomalies cause the distortion of the GPS C/A code autocorrelation function that causes differences in code tracking errors in differently-designed receivers. It was first thought that the ground network implementation for detecting these anomalies would be quite complex, especially considering the false detection and missed detection requirements associated with the continuity and integrity requirements placed upon these ground facilities. However, extensive studies and design efforts performed over the past few months have resulted in relatively practical implementations. This is because practical implementation considerations were emphasized and an effort was made to understand the requirements. This paper will lead the reader through that implementation process.
