- jandrese 1y agoIf you have a downward facing camera you can track your movement like an optical mouse by just watching the terrain. Error will creep in, but you only need to fly a few kilometers till you find something that looks like a strategic bomber.
- Sohcahtoa82 1y agoI'm dumb. I don't know why I didn't think about the cameras being used to maintain location.

- jdietrich 1y agoOperation in GNSS-denied areas is already a stock feature on many relatively inexpensive commercial drones. The manufacturers talk about it euphemistically for obvious reasons, but they're designing drones specifically for the Ukraine war. There's a huge amount of engineering effort going into building drones that can remain operational in an extremely hostile RF environment. Compensating for wind drift is a fairly straightforward software problem when you've got a fast processor, a bunch of high-resolution cameras and a laser rangefinder. https://www.autelrobotics.com/productdetail/evo-lite-enterprise-series/ https://www.autelrobotics.com/productdetail/evo-lite-enterpr...
