This review describes the use of Unmanned Aircraft Systems (UAS) for bridge inspection, with an emphasis on Multi-rotor UAS. It depicts different levels automation and autonomy during UAS operation what are achieved inspections. A description payload consisting equipment required to acquire data images is included. also contains a compendium techniques used create models from in order detect fa...

Autonomous Unmanned Aerial Vehicles (UAVs) are prohibitively expensive for use in civilian surveillance applications. This is in large part due to the manufactures need to recoup the costs of research and development. The more intelligence that is incorporated into unmanned vehicles, the more expensive it is to validate. At Cornell University an autopilot system for UAVs has been developed and ...

Before unmanned aircraft can fly safely in civil airspace, robust airborne collision avoidance systems must be developed. Instead of hand-crafting a collision avoidance algorithm for every combination of sensor and aircraft configuration, we investigate the automatic generation of collision avoidance algorithms given models of aircraft dynamics, sensor performance, and intruder behavior. By for...

Because of the key characteristics of Unmanned Aerial Vehicles (UAVs), removal of pilot, UAVs will be highly suited for repetitive, dirty, and dangerous operations. A wide range of civil and military applications are being explored in the community (Clapper et al., 2007). As a result, UAVs are given serious considerations in worldwide, making them the next step in evolution of aviation. Whateve...

This paper takes up the increasingly popular topic of drones – including unmanned aerial vehicles (UAVs), small unmanned aerial systems (sUAS), remotely piloted aircraft (RPA), and a vast panoply of commercial drones and copters – to argue that our analysis should lie not so much on drones as objects, but as assemblages of the vertical. Drones, I argue, constitute a socio-technical assemblage o...

Safety is a key factor in all aviation, and while years of development has made manned aviation relatively safe, the same has yet to happen for unmanned aircraft. However, the rapid development of unmanned aircraft technology means that the range of commercial and scientific applications is growing equally rapid. At the same time the trend in national and international regulations for unmanned ...

Measurement of aircraft attitude is a necessary step for the autonomous control of the aircraft. Autonomous aircraft are useful for a range of military and civilian purposes. A method of very low computational complexity is presented that allows the pitch and roll angles of an aircraft to be measured onboard an unmanned aircraft from real-time video of the horizon. This method can be used for m...

The University of North Dakota is developing airspace within the state where Unmanned Aircraft Systems (UASs) can be flown without an onboard sense and avoid system or Temporary Flight Restrictions (TFRs). With funding from the U.S. Air Force, a mobile ground-based system capable of detecting cooperative aircraft flying in the surrounding airspace, and the software to display information about ...

Solar-powered high-altitude unmanned platforms are highly optimized and integrated aircraft. In order to account for the complex, multi-physical interactions between their systems, we propose using integrated simulation models throughout the aircraft’s life cycle. Especially small teams with limited ressources should benefit from this approach. In this paper, we describe our approach to an inte...

This paper concerns the application of formal methods to the definition of a detect and avoid concept for unmanned aircraft systems (UAS). In particular, it illustrates how formal analysis was used to explain and correct unexpected behaviors of the logic that issues alerts when two aircraft are predicted not to be well clear from one another. As a result of this analysis, a recommendation was p...
