Super fun! Interestingly, this is how JPL was able to significantly reduce the Mars 2020 landing radius on Mars. Cameras onboard take pictures of the terrain and match that to maps to figure out where the lander is. https://www-robotics.jpl.nasa.gov/what-we-do/flight-projects...
For drones and missiles, this technique is known as Terrain Contour Matching . If terrain contour are measured optically, navigation is independent of RF jamming, unlike GNSS. https://en.wikipedia.org/wiki/TERCOM
It’s an effective a surprisingly old technique, being used on cruise missiles as early as the 1960s. It actually precedes GPS and satellite navigation by several decades. Im continuously blown away by what engineers were able to do in that era with such limited computing power. Take a look at SAGE, for example. Fun fact: the usage of TERCOM in the tomahawk missile actually limited its ability to be used in Operation…

I find it highly ironic that his is the second article on the main page right after "avoid building technologies that could be used by a police state".
Good article! Off-topic, Is Palantir doing the same thing with its internal software to geolocate?
@yassa How long did this take?
you can say that total is ~10 days of work
