Abstract:	LOng RAnge Navigation, Loran, is an attractive candidate to provide redundant services for GPS because of its complementary RNAV, stratum 1 timing, and data channel capabilities. However, for Loran to be accepted as a redundant navigation system for aviation, it must meet the accuracy, availability, integrity, and continuity standards for Required Navigation Performance 0.3 (RNP 0.3). The Loran Integrity Performance Panel (LORIPP) is a core team of experts assessing Loran’s potential to meet the RNP 0.3 performance. It applies engineering and safety analysis principles to build in safety as an integral part of the system design. The LORIPP will follow safety analysis methods similar to those used by the WAAS Integrity Performance Panel (WIPP) to conduct a rigorous Hazardously Misleading Information (HMI) analysis on Loran. This paper provides an overview of the LORIPP, the LORIPP process, and the issues being addressed relative to RNP 0.3 accuracy, availability, integrity, and continuity requirements. The LORIPP’s objective is to use rigorous analytical methods, data collection, and modeling to determine if new receiver technology and scheduled Loran station improvements can either mitigate or lower the probability of adverse effects from identified threats. The LORIPP must comprehensively and exhaustively examine every potential threat and prove that Loran, in light of these issues, meets RNP 0.3 performance requirements. Work to date indicates it is highly likely that Loran can meet these requirements.
