Without a GPS signal, I assume. Unless Google Maps is stored locally on their drone.
- defrost 3y agoFrom the original link for this post: The drone uses a camera mounted underneath it to position itself with imagery from Google Maps highlighting similarities in the images to get a rough estimate of the co-ordinates. Doesn’t Google Maps still require internet, you may ask? Google Maps allows users to download segments of maps ahead of time, usually for use when you are travelling or camping out in remote areas. In this instance, the team used this feature to their advantage, allowing the drone to continue operating regardless of having a GPS satellite connection. The entire point of such a build is to operate autonomously with local data in the presence of jamming | signal loss for other reasons.
