Performance of various predicted GNSS global ionospheric maps relative to GPS and JASON TEC data
When using predicted total electron content (TEC) products to generate preliminary real-time global ionospheric maps (GIMs), validation of these ionospheric predicted products is essential. In this study, we evaluate the accuracy of five predicted GIMs, ...
Computation of GPS P1---P2 Differential Code Biases with JASON-2
GPS Differential Code Biases (DCBs) computation is usually based on ground networks of permanent stations. The drawback of the classical methods is the need for the ionospheric delay so that any error in this quantity will map into the solution. ...
Evaluation of three ionospheric delay computation methods for ground-based GNSS receivers
GNSS observables for ionospheric estimation are commonly based on carrier-to-code leveling (CCL) and precise point positioning (PPP) methods. The CCL method is a geometry-free method which uses carrier phase to level pseudorange observation for ...
