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.
maybe it wasn’t remote controlled as much as pre-programmed?
Seems probable yes. Although it would still require GPS to keep its heading which can be jammed
Commercial aircraft have IMUs that carefully measure acceleration to get its position, IMUs are more accurate and reliable than GPS so GPS is the backup system.
“dead reckoning” is the technical term for precalculated navigation, adjusting the path only from sensors like IMUs
(unless they used stuff like cameras and POI based navigation, but that seems unlikely)
I don’t think it’s correct to say normal planes use IMU more than GPS, they’re all complementary. GPS tells the general direction and the IMU helps keeping the plane stable (no sudden jerks to turn when the GPS drifts). And ground radar tells the plane when it’s too far off the path.
“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.
I doubt an imu could have so little drift that it could hit a certain building though. I bet the gps just worked, I mean this was a place that people lived and used tech, not exactly an active warzone with gps jamming.
The IMU probably drifts by some small percentge but an intermittent GPS signal every few kilometers should ensure that it never gets too far off course.
Right, totally forgot about that
They were busy jamming the European airspace
