Timing Setting of the Differential Corrections

Navigation and correction data are time-specific information and the SBAS parameters
are defined for a specific time span. In this implementation, the SBAS corrections are
valid for 24 hours and this time span is repeated infinitely. Projection mechanism
ensures that you can select any simulation date.
Time span
There is a time slider in each SBAS dialog. With this time slider, you can "scroll" over
the time and edit, for example, the correction data at a particular time. The time span is
displayed as a gray time bar with its start and end time. The orange bar indicates the
current time span for that the SBAS parameters apply.
Figure 13-1: Timing settings
Use the following functions to define the SBAS parameters for a specific time span:
●
Set the "Time Select" value to define the start time (and the time span) the SBAS
parameters apply for.
●
Insert a page to split the time span and define parameter changes at more precise
time granularity.
1 = "Time Select" defines the page split edge
●
Remove pages to merge correction data
