Cooperative and non-cooperative Sense-and-Avoid (SAA) capabilities are key enablers for Unmanned Aircraft Vehicle (UAV) to safely and routinely access all classes of airspace. In this paper state-of-the-art cooperative and non-cooperative SAA sensor/system technologies for small-to-medium size UAV are identified and the associated multi-sensor data fusion techniques are introduced. A reference SAA...
While incremental steps are being taken to integrate unmanned aircraft systems (UAS) into the various national airspace systems, much work remains to establish appropriate regulatory infrastructure that allows UAS larger than 55 lb to operate for commerce or hire. The magnitude of that effort is compounded by the wide-ranging variety of UAS types and possible applications, as well as the diversity...
In order for Remotely Piloted Aircraft Systems (RPAS) to coexist seamlessly with manned aircraft in non-segregated airspace, enhanced navigational capabilities are essential to meet the Required Navigational Performance (RNP) levels in all flight phases. A Multi-Sensor Data Fusion (MSDF) framework is adopted to improve the navigation capabilities of an integrated Navigation and Guidance System (NGS)...
This document describes the motivation, theoretical description, development, and flight test of a system that utilizes unmanned air vehicles (UAVs) and unattended ground sensors (UGSs) to detect and image intruders on a road network. The need for completely autonomous behavior drives the design of this system so that the UAV makes onboard decisions based upon inputs from off-board sensors (unattended...
