	As defined by the International Civil Aviation Organization (ICAO), a Global Navigation Satellite System (GNSS) is a ''worldwide position and time determination system that includes one or more satellite constellations, aircraft receivers, and system integrity monitoring, augmented as necessary to support the required navigation performance for the intended operation''.<ref>ICAO International Standards and Recommended Practices, Annex 10 to the Convention pm International Civil Aviation, Volume I Radio Navigation Aids, Section 3.7.1: Definitions</ref> Current satellite navigation systems (GPS, GLONASS) were not designed to meet the real-time integrity monitoring capability required by the civil aviation navigation safety needs. For example, if a satellite develops a clock problem, GPS has no way to rapidly warn the user not to use that satellite. Sources of error such as satellite or ionospheric delays can introduce several meters of error in an aircraft's position. These errors must be corrected in real time for a precision approach where there is little or no visibility. To overcome the above limitation, several [[GNSS Augmentation\|Augmentation Systems]] have been put in place.
