Sets the parameter whose variation over the 24-hour time period is indicated on the
plot.
Long Term Correction Data Parameters
Sets the long-term correction data parameters per PRN.

Correction information on the GEO satellite location in WGS-84 coor-
dinates.

"IODE"
Issue of Data Ephemeris (IODE)
Note:
The IOD must match the IODC and IODE in the navigation
message of the GPS satellite.
To automatically synchronize the required values and ensure integ-
rity, select "Error Correction Mode = Replay Historical Data and Sync
Atmosphere & SV Errors".

Fast Correction Degradation Factor Configuration Settings
Access:
1. Select "Satellites > SBAS > Error Correction Mode > Replay Historical Data (and
Sync Atmosphere & SV Errors)".
2. Select "SV# > SV Config > Signals Configuration > Nav Msg Content > Config >
Differential Corrections".
3. For a PRN, select
