The Global Positioning System (GPS) is the key enabling technology for new air traffic management (ATM) systems. However, for civil aviation safety-of-life applications, the sensors of an ATM system using GPS must meet the required navigation performance, especially integrity. According to a new ATM system requirement, the receiver autonomous integrity monitoring (RAIM) prediction system (RPS) is an essential element for predicting GPS service quality for a 72 h period. Many web-based RPSs have been developed and are operated by civil aviation organizations around the world. However, none can autonomously provide the GPS RAIM availability information to the new ATM system. Thus, this study develops an RPS that can be integrated with the new ATM system. Airport operators can obtain the forecast results directly from the ATM system for a specific flight-information region. The system integration is validated using three years of actual operation results of the new ATM system. An evaluation of its support for additional navigation satellite constellations is also made.
