Using the Milky Way as a navigation tool
from Space Connect Podcast Hosted by Momentum Media
In 2013, Swedish researchers discovered that beetles used the Milky Way to navigate at night, realising its fixed point in the sky could help them roll dung balls in a straight line. Now, a decade later, researchers at the University of South Australia (UniSA) are using that breakthrough as inspiration for a new project aimed at improving navigation for satellites. They have developed a computer vision system that reliably measures the orientation of the Milky Way, which could one day lead to a back-up method of stabilising satellites in low light. Here, Professor Javaan Chahl, who oversaw the initiative, discusses how the plan works.
