Constructing Ionospheric Irregularity Threat Model for Korean SBAS
Single-frequency based Satellite-Based Augmentation Systems (SBAS), the augmentation of the Global Navigation Satellite System (GNSS), broadcast estimates of vertical ionospheric delays and confidence bounds on the delay errors at Ionospheric Grid Points (IGPs). Using an ionospheric irregularity undersampled threat model, the integrity bounds, called Grid Ionospheric Vertical Errors (GIVEs), mu...
متن کاملSbas Ionospheric Performance Evaluation Tests
Satellite Based Augmentation systems (SBAS) provide to Global Navigation Satellite Systems (GNSS) users with an extra set of information, in order to enhance accuracy and integrity levels of GNSS stand alone positioning. In this context, different test methods to analyze the ionospheric corrections performance are presented. The first set of tests involves two of the ionospheric calculations th...
متن کاملA New Ionospheric Estimation Algorithm for SBAS Combining Kriging and Tomography
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. Tomography reconstructs the three dimensional density of the ionosphere from the available measurements. However, there are several drawbacks to tomography: the system of equations to be solved is often und...
متن کاملIonospheric Estimation using Extended Kriging for a low latitude SBAS
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. There, it is very accurate on quiet days and allows the augmentation system so send the information in a two dimensional grid with a five by five degree resolution. However, even during quiet days,...
متن کاملIonospheric Estimation and Integrity Threat Detection
A full realization of the Wide Area Augmentation System (WAAS) is intended to provide aircraft guidance throughout the en route, terminal, non-precision and precision approach phases of ight. The most demanding phase is precision approach where vertical positioning accuracy of ones of meters is necessary. Integrity Supported by FAA Grant 95-6-005. requirements ensuring safety of life specify th...
