Update Sequence

This section describes the series of steps Visualyse Interplanetary uses to update the simulation at each time step. This well-defined procedure ensures the results generated by Visualyse Interplanetary are always consistent with the input parameters selected.

The process is as follows:

1. Update the current time using time step information
2. Set the random number seed for this time step
3. Update all the define variables
4. Update all the positions of the stations
5. Update the pointing of each antenna (except if pointing by link)
6. Update all links including:
   • Calculating the traffic profile for this link for this time step
   • Selecting the station, antenna, beam to use for dynamic links
   • Updating the pointing of any antenna that uses pointing by link
   • Calculating the wanted signal level
   • Updating the wanted signal calculation if using power control
7. Updating all interference paths
8. Updating all link groups
9. Update all statistics
10. Updating all views and outputting to file any information requested to be logged
