A Summary of GPS SPS Performance as Observed by the FAA's GPS Performance Analysis Network

J.C. Johns, Rob Conley

Abstract:	The paper begins by providing background on the FAA’s interest in GPS performance monitoring. We continue with an overview of the GPS Performance Analysis Network (PAN) program, its objectives and functional characteristics. Our performance discussion then begins with a review of position domain performance over the 15 month period be- ginning April 1, 1993 and ending June 30, 1994. This re- view consists of an evaluation of observed GPS service availability, positioning accuracy and service reliability characteristics. We then shift our focus to a discussion of observed GPS range domain characteristics, and their impli- cations on differential performance. The paper concludes with a summary of measured statistics for key SPS perform- ance parameters, compared against performance require- ments.
