As UAS technology and regulation evolve, more missions get added to the list of drone applications. Among the earliest to be identified were the missions related to the electric industry (e.g. power line surveillance, windmill inspection). Last month (February), the Oak Ridge National Laboratory released a 168p survey entitled: “An Early Survey of Best Practices for the Use of Small UAS by the Electric Utility Industry”.
Unlike other ACASs (ACAS II, ACAS X), ACAS Xu can provide both vertical and horizontal resolutions. The challenge is: how to choose between vertical and horizontal maneuvers? The choice is done by a module called Nucleus. However, little information on what Nucleus might be was publicly available until last September.
