In the presented work we compare the positioning solutions obtained using NTCM-Klobpar with those using the Klobuchar model. In low-latitude ionoepheric, 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.

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.
