This paper discusses a satellite navigation augmentation system designed for use by aviation. The ground-based augmentation system (GBAS) was originally developed as a precision approach and landing aid. This paper describes the GBAS concept, discusses the system architecture, and discusses ground and airborne equipment that compose the system. This paper also describes typical operational use of the system and the experience gained during early implementations. Advantages over the current instrument landing system technology are also discussed.
