DBUS2 and VIO: A First Step Toward Autonomous Flight

From the dawn of humanity we’ve needed to know where we are and how to get to where we want to go. Since the Phoenicians 3,000 years ago, mariners steered by the sun and the stars. Heavenly bodies have been the basis for navigation ever since. From its invention in the 1700s, the sextant, an instrument for navigating by determining the angle between the horizon and a celestial body, has been carried on ships, on jetliners (early Boeing 747s had a sextant view port in the cockpit’s roof), and on Apollo spacecraft. Today constellations of positioning satellites (GPS, GLONASS, Galileo) help us find our way. So, too, for drones, which rely on positioning satellites like GPS, along with a compass and barometer, to know where they are.

Today there is an exciting new technology for drone navigation, one that
