SBAS is sometimes synonymous with WADGPS, wide-area differential GPS. [1] The SBAS that have been implemented or proposed include: The Wide Area Augmentation System (WAAS), operated by the United States Federal Aviation Administration (FAA). The European Geostationary Navigation Overlay Service (EGNOS), operated by the ESSP (on behalf of EU's GSA).
GNSS augmentation is a method of improving a navigation system's attributes, such as accuracy, reliability, and availability, through the integration of external information into the calculation process, for example, the Wide Area Augmentation System, the European Geostationary Navigation Overlay Service, the Multi-functional Satellite ...

GAGAN is now in operational phase and is compatible with other SBAS systems such as the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS) and the MTSAT Satellite Augmentation System (MSAS) and will provide seamless air navigation service across regional boundaries.

In most areas of Ohio, the tree canopies have started to change color. Some species of trees are on track for a typical fall-change timeline, while others are changing early after the dry summer ...
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.
A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Popularly or loosely, the term "geosynchronous" may be used to mean geostationary. [1] Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, [2] or geostationary Earth orbit. [3]
