Abstract:	Satellite navigation is a critical component of the emerging world-wide air traffic management (ATM) infrastructure known as the Future Air Navigation System (FANS). This paper will discuss current trends and expected future developments in the use of satellite navigation by commercial air transport operators, and describe airline industry efforts to improve safety and derive economic benefits from navigation improvements. Some key future navigation and surveillance applications based on satellite navigation are outlined, and organizations making the transition to a satellite based Communication Navigation Surveillance/Air Traffic Management (CNS/ATM) environment are described. Air carrier difficulties in planning for these applications due to the volatility of the evolving GNSS are identified, and institutional impediments such as lack of adequate spectrum protection are addressed. A long term vision of a true Global Navigation Satellite System (GNSS) needs to be developed by the international community, and a commitment to implement that vision must be maintained by the air traffic service providers of the world. To this end, internationally accepted standards and improved procedures for GNSS operations are desperately needed to ensure that operators who have invested in this vision will obtain the expected benefits.
