Presentation Transcript

  1. UCM Aviation Aviation Satellite Based Augmentation Systems

  2. SBAS Satellite Based Augmentation System (SBAS): • Augmentation of navigation satellite systems (GNSS). Operational SBAS or Systems being built (beyond study): • WAAS (United States) (Operational) • EGNOS (Europe) (Operational) • MSAS (Japan) (Operational) • SDCM (Russia) (Non-operational) • GAGAN (India) (Non-operational)

  3. SBAS Locations

  4. WAAS Wide Area Augmentation System (WAAS) • United States • Augmentation of the global navigation satellite system (GNSS). • Operational in 2003.

  5. WAAS

  6. EGNOS European Geostationary Navigation Overlay Service • Official operations began in 2009. Initial work is being conducted to extend EGNOS to South Africa. EGNOS is interoperable with WAAS and MSAS.

  7. EGNOS

  8. MSAS Multi-functional Satellite Augmentation System • Japanese • Commissioned for aviation use in 2007. QZSS – Quasi Zenith Satellite System Designed for mobile devices within Japan. MTSAT - Multifunctional Transport Satellites Weather and aviation control satellites used by Japan and Australia.

  9. SDCM System of Differential Correction and Monitoring • Russian • Currently launching satellites and building ground stations.

  10. GAGAN GPS aided geo augmented navigation (GAGAN): • Indian • Proposed/planned implementation, not currently operational. • Operational in 2014 (planned). The system will be compatible with other SBAS systems such as WAAS, EGNOS and MSAS providing seamless air navigation across regional boundaries.

  11. GAGAN

  12. GIA63W Notes: When checking SBAS on the G1000 you may have seen: • EGNOS • MSAS • WAAS The G1000 is capable of receiving signals from all three SBAS systems.

  13. G1000 Notes: WAAS Approaches: • In order to fly a WAAS approach (LPV) you must verify/activate WAAS PRIOR TO LOADING the approach. • Checking SBAS for WAAS selection after loading the approach will not enable a WAAS approach. • The system cannot upgrade from LNAV to LPV after the approach has been loaded.
