Accurate SBAS-GPS information provided to the onboard TerrainĪwareness and Warning System/Enhanced Ground Proximity Warning System.
Performance/Area Navigation (RNP/RNAV) up to 0.3 NM approach accuracy Navigation (P-RNAV) compliance and Required Navigation Performance-Based Navigation (PBN) including Precision-Area.What else you get with an SBAS-FMS upgrade: SBAS (space-based) is opposed to GBAS (ground-based) where correction broadcasting stations are on the ground, like the DGPS, a surveying GBAS with a positioning precision up to 10 cm.ĮGNOS measuring network (SBAS for Europe area): This increases pseudo-ranging accuracy and positioning precision. SBAS in short provides for correction of GNSS radio signal propagation errors in a limited area. SBAS means using WAAS, EGNOS and other GNSS augmentation systems. Other SBAS systems in the world will also
Incorporate the Global Navigation Satellite System (GNSS) Space BasedĪugmentation System (SBAS) known in North America as the Wide AreaĪugmentation System (WAAS). The new “W” series of Universal Avionics Flight Management systems The purpose of moving from UNS-1E to UNS-1Ew is getting the SBAS capability. Main purpose: Ability to use SBAS procedures and navigation As others I believe your primary source should be your OEM.
