Minimum Detect and avoid Well Clear (DWC) guidance provides the pilot with information on the directions in which DWC is predicted to be lost and how soon. Different guidance algorithms are analyzed for their ability to provide guidance after DWC is lost. Command and status-based concepts for guidance …

The Global Positioning System has long been a great tool for militaryand, of course, civilianactivities, but the militarys heavy reliance on it also makes it a likely target. Due to the character of the satellite navigation system, security vulnerabilities exist that threaten information continuity and …

Since the introduction of the Global Positioning System (GPS), many civil and military applications have become dependent on the continuous availability of GPS-derived position and timing information. Examples comprise financial transaction systems, electrical power grids and combat management systems. …

In this paper, conflict probing has been proposed as an element of a UAS self separation concept. Conflict probing consists of predicting the future separation between own ship and hazards for a set of own ship velocity vectors -representing possible combinations of Track, Flight Path Angle (FPA) and …

Connectivity does not automatically provide NEC, but there is no NEC without connectivity. The integration of UCSs into a C2 network can significantly reduce the amount of voice communication needed to coordinate and synchronize events. The integration of UCSs into an ATMnetwork provides the basis for …
