Hello!
I am currently working on precision landing for multiple drones in a small confined area. May I know the minimum distance required between two beacons such that they land in the area they took off and not get mixed up?
If you use unique beacons they shouldn’t get mixed up. If you stage your landings you could do occupancy detection to avoid overflying or landing over another drone, this won’t guarantee repeatable placement but should at least prevent accidents.
@LupusTheCanine Thank you for the information. However, my mission requires three drones to be deployed simultaneously, with their takeoffs and landings synchronized. Since the landing area is confined, there’s a chance the drones might not land exactly where they took off. I understand that this isn’t an issue when using Aruco markers with different IDs, but I still need to find a solution to address this challenge.
Then you should worry about in flight positioning first. GNSS receivers don’t guarantee consistent error, especially between receivers. Unless you are using RTK fixed which provides relative errors in cm range you should keep a few meters (5-10) separation between drones to account for the worst case.
Using unique Aruco makers should only require passing different marker IDs to companion computers that do tracking.
