Duration

The duration of the scenario replay can be set to a number of days, hours and minutes.

Any scenario can be run in three different modes:

• Looping: The scenario will be replayed infinite times, re-starting every time after its set duration has expired.

  For this mode, the trajectory should be loop-shaped, i.e. have the same start/end point. Otherwise, an error will likely be thrown once the receiver-under-test upon the first replay is moved from the end point to the start point in an unrealistically short time.
  

• Forever: The scenario will run infinitely (the duration time will be grayed out).
  If your trajectory is loop-shaped, i.e. it has the same start/end point, the trajectory will be followed over and over again (just like in the above-mentioned Looping mode), but the simulation time will continue to elapse (contrary to the Looping mode, which will re-start the simulation time with every new scenario execution.
  If your trajectory is not loop-shaped, in this mode the receiver will travel along the last trajectory vector infinitely.

• Note: The option Endless only works, if the ephemeris option is set to Download. (See also:Ephemeris)

• One-Go: The scenario will be executed once, for the set duration.
  Upon completion of the scenario execution, GSG will return to the Main menu.
