Prerequisite: Becomes available from the marked terminal in Prodromos after progressing enough in the story. I found it available after rescuing the Moshae in A Trail of Hope.
After activating the quest, the location of all six malfunctioning drones will be marked in the map. You just need to head to the marked locations and find the actual drones. Examine them to place the beacons. Do this for all drones to complete the quest.
The drone is found on the slope behind the large boulders northeast of Site 1: Promise.
This drone is found in the hill in the middle north of the map, with a remnant site and forward station to its southeast and southwest respectively.
In Presson Dunes, past the smoking wreckage near a Kett base occupied by the kett hunter Bain Massani where you can also start the sidequest Kett’s Bane. The drone is found in the open so just follow the mission marker to find it.
Found in the far northwest corner of Presson Dunes, out in the open sands. Easily spotted.
This is found in the southwest corner of Presson Dunes, a short distance away from a kett ship wreckage. (You can find a kett surveillance device in the wreckage that’s part of the Watchers task)
This is found behind the rocks of a destroyed kett camp by the lakeshore south of Prodromos.
The quest is completed after finding the last drone.
