UAV Detect and Avoid from UTM‐Dependent Surveillance
International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.A hierarchical unmanned aircraft system (UAS) traffic management (UTM) system has deployed 45 ground transceiver stations (GTS) for UAS services in Taiwan. This UTM system covers most areas for UAV‐dependent surveillance using ADS‐B Like technology. UTM Controller can monitor all UAV flights under transparent surveillance in low airspace.
