This paper has collected 7 scenes of L band PALSAR sensor radar data of a mine in FengCheng city, jiangxi province, using the Small-baseline Subset (SBAS) method to invert the surface subsidence of th...
Although Differential Synthetic Aperture Radar Interferometry (DInSAR) has been successfully used for deformation mapping, it is easily suffered from both spatial and temporal decorrelation which limi...
Space Based Augmentation Systems (SBAS) have been developed principally to augment the Global Positioning System (GPS) for aviation and other safety of life applications.
Space Based Augmentation Systems (SBAS) have been developed principally to augment GPS for aviation and other safety of life applications. An SBAS reference network generates corrections and integrity...
This paper describes a set of MATLAB functions currently being developed for SBAS availability analysis. This toolset includes simulation algorithms that are constantly being developed and updated by ...
The original protection level equations for SBAS assumed that all actual error distributions could be easily overbounded by zero-mean gaussian distributions. However, several error sources have since ...
Safety-of-life GNSS augmentation systems must provide bounds on the probability with which hazardous navigation errors occur. This paper develops conservative bounding methods both for space-based aug...
The ionosphere causes the most difficult error to mitigate in Satellite Based Augmentation Systems (SBAS). The problem has been solved for the mid latitude regions using the thin shell approximation. ...
One can divide the existing ionospheric methods for SBAS in two categories: tomography and methods relying on the thin shell model. At first sight, tomography appears to be the right choice. Tomograph...
In Space Based Augmentation Systems (SBAS), many reference receivers are placed throughout a large region, and their measurements are combined to create a set of corrections for each ranging satellite...
Satellite Based Augmentation Systems (SBAS) are now being implemented around the world in order to improve the accuracy and integrity of Global Navigation Satellite Systems (GNSS). One of these is the...
The L1-only Satellite-Based Augmentation System (SBAS) Minimum Operational Performance Standards (MOPS) were developed long before any SBASs were certified for operation.
In the next few years GPS will start broadcasting civil signals suitable for aviation use on both the L1 and L5 frequencies. In addition, Galileo and other constellations will offer an even greater nu...
This paper describes the application of Space Based Augmentation System (SBAS) corrections and error bounds to improve the availability of Ground Based Augmentation Systems (GBAS). GBAS installations ...
SBAS and GBAS enhance standalone GNSS navigation to meet the safety and availability requirements of civil aviation. SBAS and GBAS are also freely available to other users, such as automobiles, buses,...
