摘要

Self-piloted drone traffic may be just over the horizon but for now, vehicles cannot legally fly beyond the operator's line of sight - at least not without special permission. While the Federal Aviation Administration (FAA) works to craft drone regulations and engineers work to build the features that would meet those rules, some of this new technology is opening up applications that don't involve flying across town. For example, using unmanned aerial systems (UAS) to inspect bridges, buildings, and other infrastructures or survey disaster sites doesn't necessarily require FAA compliance. An impediment to this sort of application, though, has been reliance on the GPS signals that such structures can obstruct. Without GPS, drone navigation drifts, making it difficult to register data from onboard sensors and eventually causing instability. With NASA's help, Pittsburgh-based Near Earth Autonomy is breaking the dependency drones have on GPS.
