I'm no expert but how autonomous works if there's no positioning methods involved? (To avoid GPS/GLONASS,... Jamming)

- microcolonel 8y agoFused dead reckoning can work, especially if you mix camera and IMU (or more than one IMU!).
- candiodari 8y agoSee the paper, but TLDR: stereo video depth sensing combined with fading previous measurements (so if you detected an obstacle at 1 o'clock, 2 meters out 1 second ago, it is now very likely at 2 o'clock, 1.3 meters out. This way you can limit yourself to just detecting things 2 meters out)
- pjc50 8y agoCruise missiles have an optical terrain-following system, that would be a viable approach for drones.
- kevin_thibedeau 8y agoThey use radar. https://en.m.wikipedia.org/wiki/TERCOM https://en.m.wikipedia.org/wiki/TERCOM

- tfolbrecht 8y agoSurprised nobodies mentioned celestial sensors. Celestial navigation by imaging the sky, and combining that data with a clock and compass.
- varjag 8y agoVery unreliable for ground based systems.
- fulafel 8y agoAnother technique not mentioned yet: compss augmented with local magnetic field features.
