GNSS Augmentation Systems

Purpose: To improve the accuracy and reliability of Global Navigation Satellite System (GNSS) signals
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

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

A generic term for satellite-based GNSS augmentation systems
Characteristics:
- Uses a network of satellites and ground stations to correct GNSS signals
- Provides differential corrections and integrity information
- Supports precision approach and landing capabilities
Examples:
- WAAS (Wide Area Augmentation System) in the US
- EGNOS (European Geostationary Navigation Overlay System) in Europe
- MSAS (MTSAT Satellite-based Augmentation System) in Japan

A type of performance-based navigation (PBN) procedure
Requires aircraft to be equipped with advanced navigation systems, such as GNSS and SBAS
Characteristics:
- Provides precise lateral and vertical navigation
- Enables curved flight paths and complex approach procedures
- Requires authorization from air traffic control
Benefits:
- Increases safety and efficiency in complex airspace
- Enables more precise and flexible flight routes
