Ionospheric Estimation Extended Kriging latitude SBAS
2015/6/26
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. ...
A New Ionospheric Estimation Algorithm for SBAS Combining Kriging and Tomography
Ionospheric Estimation Algorithm SBAS Combining Kriging Tomography
2015/6/26
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...
