From Destinypedia, the Destiny wiki
Awoken Beacons are devices designed by the Awoken to help navigate the Ascendant Realm. When activated outside of the Realm, they could open a portal into the Ascendant Plane or provide transport across the Ley Lines. Inside of the Ascendant Realm, they were utilized to stabilize a local area and prevent it from shifting, allowing those who wandered the planes to manipulate it.
