Generation of Klobuchar Coefficients Based on IGS GIM for Regionally Optimized Ionospheric Correction in GNSS Positioning

A practical methodology for estimating regionally optimized Klobuchar coefficients using only International GNSS Service (IGS) Global Ionosphere Map (GIM) data is proposed. The method preserves computational simplicity, enabling near-real-time corrections suitable for accurate GNSS positioning. Util...
