Satellite navigation : what does SBAS mean in fact ? Where can I find it ?
In a "quick facts" document, the IWG (Interoperability Working Group) summarizes in a very practical way the different capabilities and a worldwide map where SBAS services are available.
A Satellite Based Augmentation System (SBAS) is a navigation system that supplements Global Navigation Satellite Systems (GNSS) providing a more accurate and reliable navigation service than GNSS alone.
SBAS provides mainly the Aviation Community with two main capabilities :
- Approach Capability
- En Route Capability
To ensure seamless operation, each SBAS system has been developed to the same standard as defined by the International Civil Aviation Organization (ICAO) SARPs Annex 10.
EGNOS is the European Satellite-Based Augmentation System (SBAS) that complements the GPS system.
It is Europe's first venture into satellite navigation and a major stepping-stone towards Galileo, Europe's own global satellite navigation system for the future.
