Abstract

A GPS-denied unmanned aerial vehicle (UAV) (Agent B) is localized through inertial navigation system alignment with the aid of a nearby GPS-equipped UAV (Agent A), which broadcasts its position at several time instants. Agent B measures the signals' direction of arrival with respect to Agent B's inertial navigation frame. Semidefinite programming and the orthogonal Procrustes algorithm are employed, and accuracy is improved through maximum likelihood estimation. The method is validated using flight data and simulations. A three-agent extension is explored. [ABSTRACT FROM AUTHOR]

Abstract

By 2025, the Nova-D cargo system isexpected to regularly deliver 500-1000 kilogram payloads tothe Moon's surface when and where needed. That's why Orr's Sydney-based Advanced Navigation hasinked a deal with US space systems business IntuitiveMachines to build position-finding equipment for threelanders and two relay satellites by 2025. Space Australia's efforts to chart a course to the Moon andbeyond have taken a giant step forward thanks to cutting-edgenew navigation technology Flying to the Moon isn't a matter of plugging the coordinatesinto Google Maps and letting GPS satellites guide the way -- noris moving across the lunar surface.
