Does this have any merit aside from satisfying intellectual curiosity? I assume GPS receivers to be quite cheap these days?

- wrigby 3y agoIn the context - a hackathon sponsored by the US Department of Defense - it has great utility. GPS (and any radio-based location system) is quite vulnerable to denial by enemy jamming. This technique would by extremely relevant in a war between peers, and probably provides a much lower cost option than high-precision inertial navigation systems. Tangentially, this isn't really new - ground-pointed RADAR system combined with a good terrain dataset can also be used.

- KaiserPro 3y agoA small team managed to implement relocalisation (the technical name for this) in 24 hours is reasonably interesting. If you want to try yourself you can use colmap (https://colmap.github.io/faq.html#register-localize-new-images-into-an-existing-reconstruction https://colmap.github.io/faq.html#register-localize-new-imag...) to do the same thing. I suspect that colmap not only does lat:lon but gives you a heading as well. (well I know it does, thats how it ) Now, had they made it happen _on the drone_ that would be more interesting. It looks like it was a simulated flight, especially as there is no rolling shutter wobble. Moreover, if you want real time, you need a monster GPU, unless they've done something clever.
