Automatic Dependent Surveillance Broadcast System for Traffic Situational Awareness

摘要

An integrated communications and control system for unmanned aircraft systems (UAS) utilizes automatic dependent surveillance broadcast (ADS-B) technology. The prime objective of this system is to address safety concerns related to UAS sharing airspace with traditional aircraft. This system is capable of real-time traffic and weather updates in three-dimensional trajectories, and can be re-engineered for specific missions and applications. The system relies on GPS signals to provide increased situational awareness and a self-separation assurance system to avoid accidents. It is built around a standard Garmin GDL 90TM Universal Access Transceiver (UAT), which is independent of other aircraft avionics and requires only a power feed from the aircraft. The system is also compatible with the RANGRTM XVR system, model FDL-978-XVR, from FreeFlight~®SystemsTM.
