The international aviation community quickly realized the potential of GPS for navigation use. In xxxx, the International Civil Aviation Organization officially recognized GPS as a component of the future air navigation system. GPS rapidly became a crucial navigation component within the enroute and oceanic phases of flight. Internationally, ICAO recognized the Russian satellite navigation system, GLONASS, as a component of GNSS. The European Union and other countries have begun or plan to begin development of satellite navigation systems. All of these systems promise to contribute to the overall global navigation satellite system or GNSS.As accurate as GNSS is, it is currently incapable of supplying enough integrity to be used during the most strenuous phase of flight, precision instrument approach. Integrity is defined as the probability that the information provided by a system will not be hazardously misleading. In other words, if the system breaks, what is the likelihood that this system could send a user bad data that could cause a dangerous situation? For a new navigation system in the United States, this situation can only have a one in ten million chance of happening.The FAA has implemented GNSS, SBAS, and GBAS in the form of GPS, WAAS, and LAAS. The FAA created the WAAS program in xxxx to primarily provide the necessary integrity to utilize GPS signals for precision approach. The WAAS consists of a network of precisely surveyed wide area reference stations (WRS). These reference stations monitor GPS satellites to determine errors in the GPS satellite signal. Each reference station relays the information about the GPS satellites to the WAAS wide area master stations (WMS). There are two WMS, one located on the East Coast, one on the West Coast. The master station uses the information collected by the reference stations to develop corrections to the GPS position information and provides timely notification of unreliable GPS data. These corrections are sent to ground uplink stations (GUS) where they are transmitted in the form of a WAAS correction message to a Geostationary Earth Orbit (GEO) satellite
