Looking at your gunsmith rank it appears your Hunter has 3 relics and your Titan has 2. Each relic gives 200xp to rep. If you haven't done any of the field weapon tests then that is the only way to kinda keep track. Once you get all four just set destination to cosmodrome and first firewall will pop up. Recent update makes it so you don't have to wait for sleeper, black spindle, or no time to explain. Can do these anytime you want.
