Collecting Survey Drone Modules is one of the Collectables quests in Horizon Forbidden West. To complete the Survey Drone Modules quest, you need to find and capture each of the Survey Drones scattered about the map, and reconnect them at The Base. You can’t reconnect them until after you’ve completed The Eye of the Earth main quest.
The locations of all ten Survey Drones are as follows. Check out the linked guides for more detailed descriptions and maps:
Survey Drone: No Man’s Land (Survey Drone Module 024)
Close to a Thunderjaw Site between Rebel Outpost: Jagged Deep and Jagged Deep Delve. You need to jump from a wooden platform high in the rocks. Sneak past the Thunderjaw if you daren’t fight it.
Survey Drone: Plainsong (Survey Drone Module 047)
Hovering over a small fort northeast of Plainsong. You need to jump from the top of the fort’s walls to capture it. You can either ignite the Firegleam on the fort’s door to get inside, or scale the cliffs to get over the walls.
Survey Drone: The Dry Yearn (Survey Drone Module 143)
In the dusty desert northwest of The Base. You need to climb the mountain north of the Shellsnapper site, and jump from the shelter at the top.
