What kind of drones are we talking about here? Looking at the demo in the site, it seems you are talking about passenger drones? Regardless, in a previous smart city project I did, we have a similar concept, although it wasn’t passenger ones but un-crewed ones, including consumer or even heavy-lift ones, and their bases is basically a “nests” where the drone can land, charge the batteries (either wirelessly or through auto activated actuators to connect to battery outlets), or even deliver some packages, the challenges were: - Regulations: obtaining that was a hassle, as this counts as a BVLOS (beyond visual line of sight), for passengers ones I assume it is even harder, and while you might say this is on drones operators not our concern, then your ports won’t be used! - Safety: from making sure the drone will actually land on that spot, all the way to ensure it won’t hit someone during taking off/landing is a big job, since it will be autonomous or semi at least, you won’t have someone standing near the landing spot (or nest) all the time to go through all the checklist before taking off or landing. - Security: Ensuring no one is damaging your drone, stealing it, or damaging your landing spot or vandalizing some sensors like cameras in there. - Connectivity: while our project was about flying over cellular (5G) in an urban area, we had so many connectivity issues, flying over RC is worse, you might end up with drones crashing on buildings due to C2/telem loss, or you have an emergency landing over the people (deadly for some heavy-lift drones), or crashing on the way to the launch site after safety is triggered due to loss of battery, this point might be different for you if you are targeting passenger ones though. - You need to standardize a couple of things, power delivery, power outlets chargers, and so on, both on your ports and drones manufacturers abide with, and it’s not an easy task, look at electric cars as an example. - Our project lead to other projects about regulating drones in the skies so you won’t end up crashing other drones/aircraft. - I am sure there are more challenges in your case too like, is it worth from a property owner perspective, among others.
