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. Initial download of the metrics may take a while. Showing klobucbar 17 references.

Kumar DabbakutiN. In the presented work we compare the positioning solutions obtained using NTCM-Klobpar with those using the Klobuchar model. Data correspond to usage on the plateform after References Publications referenced by this paper. Services Same authors – Google Scholar. In low-latitude modell, 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.

From This Paper Figures, tables, and topics from this paper. 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 presented algorithm has the potential to continuously improve the accuracy of GPS single frequency mass market devices with only little software modification. The root mean squared deviation of the klobucar position errors are found to be about 0.
