Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for obtaining a sample Light Detection and Ranging (LIDAR) profile generated by a drone; selecting a reference position based on the sample LIDAR profile; determining a LIDAR profile-based translation and rotation relative to a reference LIDAR profile of the reference position; determining an image-based translation and rotation relative to a reference image of the reference position; determining whether the LIDAR profile-based translation and rotation and the image-based translation and rotation satisfy a similarity threshold; and verifying, using a result of the determination, a predicted position of the drone.
