Before GPS, cruise missiles used photographs of the terrain they expected to navigate and a camera. The photos were state secrets back then; today they're easily accessible for the entire planet. Miniature computers are also far more power and more capable of the processing needed for navigating using photos and a camera. It'd take some R&D to develop, but it's certainly possible.
Also, "falling out of the sky" can still be an effective weapon if you plan for it.

- RealityVoid 8y agoWhile certainly possible, it would take the pool of people able to build it down at least an order of magnitude. I can say so with the experience of a guy who build drones and also tried working with some vision stuff for drone indoor positioning. It simply is far harder to do. GPS guidance you can do it in an slow evening. Most of the measures intended to stop access to explosives, weapons and generally dangerous things are not able to do so 100% but simply make the cost of that access high enough MOST malevolent actors will simply not afford it.
