Time Scale, Time Select ← Edit Grid ← MOPS-DO-229D ← Atmosphere
Displays a time scale (the gray bar) and the current time span (the orange bar).
An arrow indicates the current time ("Time Select").
Projection mechanism ensures that you can select any simulation date. Hence, date
information is irrelevant and not displayed.
Insert/Delete Page ← Edit Grid ← MOPS-DO-229D ← Atmosphere
"Insert Page" splits the current page at the current "Time Select" moment.
"Delete Page" removes the current page; the time span of the previous page is exten-
ded and the content of the new page corresponds to the content of the previous page.
Display ← Edit Grid ← MOPS-DO-229D ← Atmosphere
Toggles between indication of the vertical delay and GIVEI values.
Longitude, Latitude ← Edit Grid ← MOPS-DO-229D ← Atmosphere
Indicates the geographic coordinated of the selected ionospheric grid point IGP.
GIVEI/Vertical Delay ← Edit Grid ← MOPS-DO-229D ← Atmosphere
Sets the grid ionospheric vertical error indicator "GIVEI" and the "Vertical Delay" values
of the current IGP.
Changes are applied immediately.
To save the ionospheric grid, select "Export Grid".
To restore the predefined ionospheric grid for the MOPS-DO-229 model, select "Import
Grid > Add File > Predefined Files > 19_02_14_mixed > Import".
Export Grid ← MOPS-DO-229D ← Atmosphere
Access: select "Export Grid > set the filename > Export".
