From Bars To Blue Sky: DOT Explores Cellular Networks For Drone Safety

Operation of unmanned aircraft systems (UAS) – commonly known as drones – is rapidly expanding into airspace traditionally occupied by manned aircraft, creating an urgent need for new safety technologies. In particular, the need for ensuring reliability of communications and navigation capabilities has prompted discussion. In response, the U.S. Department of Transportation (DOT) has launched the Mobile Network Aviation Assessment Program (MNAAP), an initiative that seeks to answer the question: Can the commercial cellular networks already used every day help keep aircraft – manned and unmanned – safely separated in shared airspace?

The Problem MNAAP Is Designed to Solve

Aviation safety has long relied on a patchwork of radar, human observers and Global Navigation Satellite System (GNSS)-dependent electronic conspicuity signals. These systems were largely designed to ensure safe operations around airports, where most manned flights begin and end. Drones, however, do not require
