摘要

The Local Area Augmentation System (LAAS) and the Wide Area Augmentation System (WAAS) are being developed by the U.S. FAA to provide satellite navigation performance compliant with the stringent requirements for aircraft precision approach and landing. A primary design goal of both systems is to insure that signal-in-space failures are detected by ground facilities and affected measurements are excluded before differential corrections are broadcast to users. One such failure is unintentional interference or intentional jamming in the GPS frequency band. To protect integrity, ground facilities must quickly detect the presence of interference that fall within the restricted zone defined by LAAS and WAAS system requirements and thus may be hazardous to users. To protect availability, ground personnel must also be able to locate and deactivate the interference source. In order to serve this purpose, the prototype Generalized Interference Detection and Localization System (GIDL) has been developed. This prototype includes four antennae and RF sections slaved to a common clock to allow detection and determination of three-dimensional interference location. The paper describes test results from a real-time demonstration of the GIDL system. In this test, a calibrated wideband noise source is utilized as GPS jammer and is moved around the field between a set of pre-calibrated locations, and the realtime GIDL display provides up-to-date estimates of the location of this interference source to within the limits predicted by the accuracy analysis.
