The NTCM-Klobpar model is a new ionospheric model for the Galileo Open Service that provides excellent performance similar to the current recommended solution using NeQuick-G, while its computational complexity is highly reduced.

NTCM-G is a fully compatible algorithm used to compute ionospheric corrections for Galileo single-frequency users.
