Abstract:	This paper describes the development of the Precise Positioning Service (PPS) Performance Standard (PS). The PPS PS will be the first place the PPS signal-in-space (SIS) performance is documented in a publicly releasable form. It begins with a brief background explanation of the rationale for differences between and among the GPS Interface Control Documents (ICDs), the Standard Positioning Service (SPS) PS, and the PPS PS. The paper then transitions to a discussion of the proposed PPS SIS performance standards in the PPS PS. Significant new performance standards include an alternate configuration of the 24-slot constellation, a new and more meaningful way of specifying SIS range accuracy, Wide Area GPS Enhancement (WAGE) accuracy improvement, single-frequency ionospheric delay model accuracy, new SIS range rate and range acceleration accuracies, SIS integrity failure probabilities as a function of the broadcast User Range Accuracy (URA) value, and SIS continuity. The analyses and derivations supporting each of these new performance standards are also described for future traceability. This paper concludes with a brief discussion on the importance of the PPS PS for integrators, end users, and navigation safety authorities.
