Derivation of Ranging Source Integrity Requirements for the Local Area Augmentation System (laas)
Several satellite latent fault modes can cause errors that may not be removed by pseudorange corrections or be detected unless special augmentation-based integrity monitors are employed. The error classes resulting from satellite fault modes are distorted signal waveform, uncorrectable ephemeris error, excessive clock acceleration, excessive code-carrier divergence, and low signal power. The pa...
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,...

متن کاملCorner cutting with trapezoidal augmentation for area-preserving smoothing of polygons and polylines
Recently, a new subdivision method was introduced by the author for smoothing polygons and polylines while preserving the enclosed area [Gordon D. Corner cutting and augmentation: an area-preserving method for smoothing polygons and polylines. Computer Aided Geometric Design 2010; 27(7):551–62]. The new technique, called ‘‘corner cutting and augmentation’’ (CCA), operates by cutting cornerswith...
