متن کاملFlight Trials of the Wide-Area Augmentation System (WAAS)
The Wide-Area Augmentation System (WAAS) is being rapidly developed by the Federal Aviation Administration for supplemental operational use in 1997. In time, it will be a primary navigation aid for all phases of flight down to Category I precision approach. The WAAS will include a network of approximately 20 to 30 Wide-area Reference Stations (WRSs) distributed around the National Airspace Syst...
متن کاملA Novel Interference Rejection Method for GPS Receivers
This paper proposes a new method for rejecting the Continuous Wave Interferences (CWI) in the Global Positioning System (GPS) receivers. The proposed filter is made by cascading an adaptive Finite Impulse Response (FIR) filter and a Wavelet Packet Transform (WPT) based filter. Although adaptive FIR filters are easy to implement and have a linear phase, they create self-noise in the rejection of...
متن کاملGPS Ephemeris Verification for Local Area Augmentation System (LAAS) Ground Stations
Certain types of satellite failures, such as broadcast ephemeris messages that do not correspond to true satellite locations, can be difficult to detect by a Local Area Augmentation System (LAAS) ground facility (LGF) because satellites are observed from reference antennas that are very close together. Although ephemeris failures large enough to threaten LAAS user integrity should be very rare,...
