GNSS Opportunities in Aviation
The document discusses the role of GNSS (Global Navigation Satellite System) in enhancing performance-based navigation in aviation, highlighting current and future implementation of EGNOS and Galileo systems. It emphasizes key trends including the shift from traditional to GNSS navigation solutions, increasing safety, and improved operational efficiency. By 2018, significant expansions in LPV (Localizer Performance with Vertical guidance) procedures and devices are anticipated, enhancing communication, navigation, and surveillance applications in aviation.

Editor's Notes
- #5 EGNOS V3 is planned to offer significantly improved service performance (accuracy, continuity of service, lower vertical alert limit, coverage) thanks to new signals and Galileo satellites In case of an emergency in aviation segments, time is of the essence and first response is critical. Galileo will complement the existing network of satellites tasked to receive and transmit distress signals, decreasing response times. Galileo will also offer a return link confirming the distress signal was received.
