SBAS Interoperability Demonstration
| Abstract: | The Wide Area Augmentation System (WAAS) was placed in service in July 2003, becoming the first Satellite Based Augmentation Systems (SBAS) for the Global Positioning System (GPS.) Over the past several years, SBAS development has continued, producing systems in Europe and Japan and new planned systems in India, Russia and China. Standards have been implemented to insure that these systems are interoperable, so that users can operate seamlessly when conducting flight operations between coverage areas of the different systems. This paper provides the results of a flight demonstration of SBAS interoperability conducted by the Federal Aviation Administration (FAA.) In the summer of 2012, the FAA conducted several flights in order to demonstrate SBAS interoperability. An instrumented FAA aircraft was flown from the U.S. to airports in the coverage areas of EGNOS and MSAS. The aircraft was equipped with several WAAS receivers which have received an FAA TSO approval for use in en route, NPA, and LPV operations. Data were collected as the aircraft flew through the transition area from one SBAS region to the other, and also during approaches to airports with available SBAS procedures. In the North Atlantic, two oceanic crossings were flown in each direction to explore the transition regions of overlapping coverage, and several LPV approaches were flown to Alderney, in the Channel Islands. In the Pacific, the aircraft was flown to Guam to observe performance in an MSAS-only environment. |
