Klobuchar-Style Ionospheric Coefficients
In the presented work we compare the positioning solutions obtained using NTCM-Klobpar ionosphfric those using the Klobuchar model. The presented algorithm has the potential to continuously improve the accuracy of GPS single frequency mass market devices with only little software modification. Space weather effects on GNSS and their mitigation.

Topics Discussed in This Paper. In low-latitude regions, 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. The root mean squared deviation of the 3D position errors are found to be about 0. Initial download of the metrics may take a while.
The model is driven by a parameter computed from GPS Klobuchar model and consecutively can be klovuchar instead of the GPS Klobuchar model for ionospheric corrections. Approach for near-real-time prediction of ionospheric delay using Klobuchar-like coefficients for Indian region.

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.
