Geography. As GPS became ubiquitous in technology use throughout the world, similar
systems called generically as Satellite-Based Augmentation System (SBAS). A SBAS is a
system that supports wide-area or regional augmentation through the use of additional
satellite-broadcast messages. Such systems are commonly composed of multiple ground
stations, located at accurately-surveyed points. The ground stations take measurements of one
or more of the GNSS satellites, the satellite signals, or other environmental factors which may
impact the signal received by the users. Using these measurements, information messages are
created and sent to one or more satellites for broadcast to the end users.
general term referring to any such satellite-based augmentation system, under the International
Civil Aviation Organization (ICAO) rules a SBAS must transmit a specific message format
and frequency which matches the design of the United State’s Wide Area Augmentation
System. See Figure 5
As noted this system was originally developed for the U.S. and Northern Hemisphere
While SBAS designs and implementations may vary widely, with SBAS being a
