From my work experience its like this: 1. Assemble commands to run 2. Run the commands and see results in the 15 minute window 3. See if you can do more commanding in the minutes you have left 4. Make a new plan, wait for next pass, and goto 1

For LEO satellites, that usually means you have 2 blocks of 3 13 minute passes, when the groundstation is in The Netherlands. For a Svalbard groundstation, you get a lot more, but still 13 minute or less passess.
