At time of making, this video shows the best areas to farm/rank up with elite dangerous federation.
Only you reach 100% on your rank progress bar found on the System panel, you will be able to get a navel mission, this will grant the next Rank as well as any permits you can unlock for that Rank. While waiting on the Naval mission to show up continuing to do federation missions will give you points on your next rank progression, even though the game will say progression 100% on the current rank!
