NTCM G: Galileo single-frequency ionospheric corrections model

The Neustrelitz Total Electron Content (TEC) Model for Galileo satellite navigation systems NTCM G can be used to determine Galileo single-frequency ionospheric corrections.

The Neustrelitz Total Electron Content (TEC) Model for Galileo satellite navigation systems NTCM G can be used to determine Galileo single-frequency ionospheric corrections. It is proposed as an alternative to the reference algorithm NeQuick G. The model was developed by the German Aerospace Center (DLR) and validated with the support of ESA, and the Joint Research Centre (JRC) of the European Commission. The reduced complexity and runtime of the NTCM G algorithm are beneficial, in particular in user-segments where the equipment has limited resources available, like for civil avionics receivers or location-based services for smartphones.
