Space Weather Space Clim. Space weather effects on GNSS and their mitigation. In low-latitude klobucjar, such as India and Brazil, correction of the ionospheric delay based on these coefficients is not accurate because of the large gradients and complex dynamic ionospheric behavior.


Our investigation using worldwide ground GPS data from a quiet and a perturbed ionospheric and geomagnetic activity period of 17 days each shows that the hour prediction performance of the NTCM-Klobpar is better than the GPS Klobuchar model in global average.

Klobuchar Ionospheric Delay Model – File Exchange – MATLAB Central

Kumar DabbakutiN. In the presented work we compare the positioning solutions obtained using NTCM-Klobpar with those using the Klobuchar model. Approach for near-real-time prediction of ionospheric delay using Klobuchar-like coefficients for Indian region.

The root mean squared deviation of the 3D position errors are found mlobuchar be about 0.

The model is driven by a parameter computed from GPS Klobuchar model and consecutively can be used instead of the GPS Klobuchar model for ionospheric corrections.
