F Ionospheric Grid File Format

Customized ionospheric grids can be exported and saved as *.iono_grid files.
Such files can be imported and used for the simulation of the MOPS-D0-229D iono-
spheric model. If imported together with *.ems or *.nstb files, custom ionospheric
grid files can also be mixed with the SBAS files, for example to create an ionospheric
grid covering the entire world map.
The *.iono_grid files are XML files in a Rohde & Schwarz proprietary file format .
They contain Vertical Delay, GIVEI value pairs with 5° and 15 minutes resolu-
tion.
