Need help on finding Marauder base!

Im in bad shape and need some help.
Im trying to use the capsule space tracker installed on my ship in act2 two to track a marauder ship to their base. Im hanging out in Firefrost waiting for marauders. When they attack I formate with them before they flee, but after a few seconds of following them they disappear off my contact list. Need some help, what am I doing wrong?
