Previous article Next article. Approach for near-real-time prediction of ionospheric delay using Klobuchar-like coefficients for Indian region. 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.


Our ionosheric 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.
