SmartPath – The next generation of precision landing guidance technology

The SmartPath Precision Landing System provides differential GPS corrections and integrity for all satellites in view and approach path information covering all runway ends

• SmartPath accuracy enables closely-spaced parallel and curved path approaches
• Improved navigation accuracy over Instrument Landing Systems (ILS)
• Increases airport capacity by eliminating ILS hold short-zones – it is estimated that aircraft will save one to two minutes of taxi-time per flight by not having to hold-short
• Substantial maintenance saving – one SmartPath system installed in a typical airport can yield maintenance savings of up to $400,000 annually when compared to ILS
• More flexible than ILS – one GBAS can broadcast 26 unique approaches covering all runways at an airport
• Utilizes differential GPS, and broadcasts both pseudorange corrections for each satellite in view, as well as approach path information in a digital broadcast
• One GBAS can cover all ends of all qualified runways. The ILS covers only one end of one runway, requiring additional installations for complete coverage
• Supports offset and segmented approaches for displaced threshold landings
• Most current-production Airbus and Boeing aircraft are now equipped with GBAS avionics or offer GBAS as an option
• Future upgrades include ability for CAT III approaches
