Unmanned Aerial Vehicle (UAV) refers to a class of aircrafts that can fly without the onboard presence of pilot. They can be flown by an electronic equipment present on the vehicle and on a GCS (Ground Control Station), or directly from the ground. In this last case it is common to associate the system with the expression RPV (Remotely Piloted Vehicle), since the vehicle is remotely piloted and operated by radio-controlled devices. In literature other terms are adopted to indicate such category of vehicles, such as: Drone, ROA (Remotely Operated Aircraft), UVS (Unmanned Vehicle System). In March 15, 2012, Federal Aviation Administration (FAA) Next Generation Air Transportation System Joint planning and development office has issued "Next UAS Research Development and Demonstration Roadmap", which points out that, satellite navigation system will be one of the key technologies in the future UAV. BeiDou Navigation Satellite System is called BeiDou System for short, with the abbreviation as BDS. When fully deployed, the space constellation of BDS consists of five Geostationary Earth Orbit (GEO) satellites, twenty-seven Medium Earth Orbit (MEO) satellites and three Inclined Geosynchronous Satellite Orbit (IGSO) satellites. By the end of 2012, there are five GEO, four MEO and five IGSO BeiDou navigation satellites in orbit. BDS Signal-In-Space Interface Control Document (ICD) (version 2.0) is issued by the China Satellite Navigation Office on December 27, 2013. At the same time, the performance specification for public service (version 1.0) of BDS is also issued. In China, BDS will be used as the primary navigation system for civil and military aviation. As low-altitude airspace open in China, more and more UAVs will be appeared, how to manage them and guarantee them to flight safely and efficiently is an urgent and important problem. Therefore, in the paper, we will study on BDS application on UAVs Air Traffic Management. The core research contents include two parts as follows. First, study the navigation application of BDS SBAS on UAVs. Second, study the communication application of BDS Short message on UAVs.
