In a sharp escalation of its drone campaign targeting strategic industries deep inside Russia, Ukraine seems to have fitted Cessna-style light planes with remote controls, packed them with explosives and flown at least one of them more than 600 miles to strike a Russian factory in Yelabuga, 550 miles east of Moscow.
Ironically, the Russian factory produces—you guessed it—drones.
Russians on the ground recorded the shocking scene as the light plane dove onto the sprawling Alabuga Special Economic Zone industrial campus, where workers assemble Iranian-designed Shahed drones that, just like Ukraine’s DIY Cessna-style drone, can range as far 600 miles with an explosive payload.
“Dead reckoning” as in “dead reckoning” as in “deduced reckoning”. It’s the same kind of navigating people have done on boats for millennia. You start from a known point and move in a specific direction at a known speed for a specific amount of time. Then you change your speed and/or direction for another specific amount of time. And so on. If you have the ability to do so then you update your known position along the way via known landmarks you might pass.
Yeah but the errors creep up, so if you don’t see the islands of hope after sailing for 18 days at speed x, you’re fucked :-)
That’s why you have several systems, like gps to periodically try to get a good signal, or manual override.
