- Methods:
- Satellite-based augmentation (SBAS)
- Ground-based augmentation (GBAS)
- Combination of both
- Benefits:
- Improved accuracy and integrity
- Increased availability of GNSS signals
- Enhanced safety and efficiency in aviation
EGNOS (European Geostationary Navigation Overlay System)
- A European SBAS system
- Comprises:
- Three geostationary satellites
- A network of ground stations
- A control center
- Functions:
- Corrects GNSS signal errors
- Provides integrity information
- Supports LPV (Localizer Performance with Vertical Guidance) approaches
- Benefits:
- Enables precision approach and landing capabilities
- Improves safety and efficiency in European airspace
SBAS (Satellite-Based Augmentation System)
- A generic term for satellite-based GNSS augmentation systems
- Characteristics:
