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

Klobuchar-Style Ionospheric Coefficients

In the presented work we compare the positioning solutions obtained using NTCM-Klobpar with those using the Klobuchar model. Autonomous single-frequency ionospheric correction model for safety-of-life applications. The current usage metrics is available hours after online publication and is klobbuchar daily on week days.
