Service areas of satellite-based augmentation systems (SBAS) A list of GNSS and SBAS satellites received by a smartphone. Satellite-based augmentation systems (SBAS) support wide-area or regional augmentation through the use of additional satellite-broadcast messages. Using measurements from the ground stations, correction messages are created ...
GNSS systems that provide enhanced accuracy and integrity monitoring usable for civil navigation are classified as follows: [5] GNSS-1 is the first generation system and is the combination of existing satellite navigation systems (GPS and GLONASS), with Satellite Based Augmentation Systems (SBAS) or Ground Based Augmentation Systems (GBAS). [5]
The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. [2] It is a system to improve the accuracy of a GNSS receiver by providing reference signals. [3]
The European Geostationary Navigation Overlay Service (EGNOS) is a satellite-based augmentation system (SBAS) developed by the European Space Agency and EUROCONTROL on behalf of the European Commission. Currently, it supplements GPS by reporting on the reliability and accuracy of their positioning data and sending out corrections.
Artist’s rendering of MSAT-1. Multi-functional Satellite Augmentation System (MTSAT or MSAS) [1] is a Japanese satellite based augmentation system (SBAS), i.e. a satellite navigation system which supports differential GPS (DGPS) to supplement the GPS system by reporting (then improving) on the reliability and accuracy of those signals.
Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do. A number of weather satellites are also present in geosynchronous orbits. Not included in the list below are several more classified military geosynchronous satellites, such as PAN.

L1 SBAS. L1 SBAS augments GPS and is an Aeronautical Radio Navigation Service (ARNS). L1 SBAS augments GPS and is an Aeronautical Radio Navigation Service (ARNS). This signal will be used for Safety-of-Life applications and therefore needs to be certified by the National Aviation Authorities—that is, the Australian Civil Aviation Safety ...
