Programmierter Multikopter fliegt selbstständig durch die Arktis

Forscher führen auf aktueller Polarstern-Expedition autonomen Multikopter-Flug in der Framstraße durch

(PresseBox) (Bremerhaven, )
Wie bringt man ein Fluggerät in den Weiten des Arktischen Ozeans ans Ziel, wenn der Kompass keine zuverlässigen Positionsdaten liefert? Ingenieure an Bord des Forschungseisbrechers Polarstern des Alfred-Wegener-Instituts programmierten einen Multikopter so, dass er trotz Missweisung des Erdmagnetfeldes nahe des Nordpols navigieren kann. Einen ersten erfolgreichen autonomen Testflug nebst Landung feierten die Wissenschaftler kürzlich auf einer Eisscholle.

"Die autonome Navigation stellt in hohen Breiten eine große Herausforderung dar", sagt Sascha Lehmenhecker, Ingenieur am Alfred-Wegener-Institut, Helmholtz-Zentrum für Polar- und Meeresforschung (AWI). "Die Navigation erfolgt mittels Magnetsensoren. Die Feldlinien des Erdmagnetfelds zeigen jedoch in Pol-Nähe nahezu senkrecht zum Erdboden, so dass eqvk crljzv Yiqfftwaxz zczugbtio ajq.
