These generally just use RTK and a base station; nothing interesting and extremely easily rejected by EW (since they need both accurate global positioning signal _and_ RTK signal).

Inside-out SLAM strategies and on-device ML are much more interesting and are starting to trickle into COTS drones. For example, the latest DJI drones all use SLAM for return-to-home even when GPS denied: https://www.facebook.com/reel/440875398703491 , and the latest Matrice 4 enterprise drones also have end-user ML model runtimes that can fine-tune flight plans using user-provided logic.

Inside-out last-second targeting is also very popular in Ukraine, with off-the-shelf "find the nearest car/person in analog video, lock to it on signal lost, and send Betaflight MSP stick commands to hit it" modules readily accessible on Aliexpress.
