"G-Nut/Tefnut" is the end-user application designed to estimate tropospheric path delays in various processing modes. Below applications are implemented using the G-Nut core library developed at the Geodetic Obsevatory Pecny. A comparison of supported capabilities is available in the feature matrix. All applications are released under the GNU General Public Licence.
Figure shows an example of Tefnut's real-time troposphere monitoring in real-time mode using IGS RTCM clock and orbit corrections.

INSTALLATION - instruction for the installation.

SUPPORT - the current lite version is provided as a beta release and still undergoes final consolidations of the core library. The software is provided "as is" and without warranty of any kind. The support is given on a best-effort basis only.
