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.
