Given these are static targets, it might be possible to relay precise GPS information from that morning’s satellite data. No real time intelligence required. Just dead reckoning to the target coordinates.
- Sohcahtoa82 1y agoDead reckoning in a drone would be a nearly impossible feat considering how variable wind can be.
- 0cf8612b2e1e 1y agoThe wrong term, but I know there has been extensive research in maintaining accuracy without GPS.
- 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...
