6 Simulation Time

The default system time in this simulation is given in the UTC (Universal Time Coordi-
nates) time base. The simulation start time is thus defined as date and time and is set
to 19.02.2014 at 06:00:00 am.
Simulation start time
You can change the simulation start time as you can change the time basis at any
time. The time is then automatically recalculated and displayed in the selected time for-
mat.
If the satellite constellation comprises SVs from different navigation systems, you can
observe the current simulation time converted into the time basis of each of the
enabled GNSS systems at a glance.
Time conversion parameters and leap second
Time conversion parameters are zero and first order system clock drift parameters and
the current leap second.
The leap second describes the difference between the GPS, Galileo, GLONASS or
BeiDou system time and UTC system time. The simulation requires only the date and
sign of the next leap second, further calculations are performed automatically.
Simulating time conversion errors
Per default, the time conversion between the time basis excludes conversion errors
and drifts between the time basis of the GNSS systems. We recommend that you use
the default configuration, without system time offset or time drift.
If you aim to simulate deliberate erros and change the time conversion settings, see:
