• Abstract:
  The Volpe Center designed, implemented, and deployed a Global Positioning System (GPS) Receiver Autonomous Integrity Monitoring (RAIM) prediction system in the mid 1990s to support both Air Force and Federal Aviation Administration (FAA) use of TSO C129 receivers. That system is currently hosted at the U.S. NOTAM Office at the Air Traffic Control System Command Center (ATSCC) in Herndon, VA. The system is used to predict TSO C129 GPS RAIM availability for non-precision approach (NPA) operations for a group of military and civilian airfields. GPS RAIM outages for military airfields are available as M-Series NOTAMs and for
  
  civilian airfields. They are available as aeronautical information from Automated Flight Service Stations.
  
  Advisory Circular (AC) 90-100A, published March 1, 2007, requires that a pilot check GPS RAIM availability for Area Navigation (RNAV) routes, departures, and arrivals if RNAV compliance is based solely on TSO C129 equipment [1]. Previously, TSO C129 GPS RAIM availability predictions for the en route and terminal phases of flight were not available. The FAA requested that the Volpe Center develop a web-based TSO C129 GPS RAIM prediction capability in order to provide en route and terminal predictions to the general public. The status of en route and terminal GPS availability is graphically displayed on the web site www.raimprediction.net. This web site is hosted at the Volpe Center in Cambridge, Massachusetts.
  
  This paper describes, in five sections, the design and uses of the AC 90-100A GPS RAIM prediction website. First, the paper addresses the requirements of AC 90-100A, and whom it affects. Second, the paper describes the overall system architecture. Third, it will further detail of each of the system components, including the GPS RAIM service volume model, the outage database, the web based graphical user interface, and the communication channels between them. Finally, it examines future plans and enhancements for the AC 90-100A GPS RAIM prediction system as a whole.
