How the layers fit together

A single routine flight can require a long chain of dependent decisions before takeoff: boundaries, exclusion zones, aircraft and terrain settings, safety buffers, the route itself, coverage checks, and battery and refill timing. None of it is hard on its own. There is just a lot of it, it starts from scratch on every job, and one wrong value can cost an aircraft.

GPS is not available everywhere the work is. Transmission corridors, tall structures, enclosed spaces and areas under interference all weaken or remove the fix, and that is often exactly where the inspection needs to happen.

Most drone autonomy available today depends on an uplink and remote inference. That is the component most likely to fail at the moment it matters, and it caps range, adds latency, and limits where an aircraft can be trusted to operate.
