ABSTRACT The U.S. Coast Guard is developing an airborne, real-time, all-weather, day/night remote-sensing system that will detect oil pollutants and identify violating vessels. The system, designated “Aireye,” will be installed on six of the 41 new Falcon 20G jet aircraft, (military designation HU-25A) purchased by the Coast Guard to replace the aging HU-16E Grumman Albatross as its medium-range surveillance aircraft. The sensor system will include a side looking airborne radar, two-channel infrared/ultraviolet line scanner, aerial reconnaissance camera, airborne data annotation system, and a control, display and record console. To identify polluting vessels at night, an active gated television (AGTV) also is being developed for inclusion in the Aireye system. The AGTV will use a one-watt, pulsed, lead vapor laser illuminator and will be capable of recording vessel names at night from a slant range of 700 meters. In addition to an active and passive mode, the AGTV will be capable of both computer and manual target acquisition and tracking. Each of the sensors will produce annotated, hard copy imagery suitable for prosecution of polluting vessels.

The China Coast Guard vessels assume the search and rescue mission in Chinas coastal waters. Simulator training is an effective means to improve search and rescue efficiency. Through the analysis of the actual search and rescue process, a search and rescue training simulator is designed for the China Coast Guard vessels. The system structure, the search model, and the SART hardware simulation technology are introduced in the paper.

Abstract The gradual empowerment of the Libyan Coast Guard through EU training and funding has introduced them as a new actor in the Central Mediterranean amongst other civil and military actors intervening to prevent loss of life at sea. This article examines the contested recognition of the authority of the Joint Rescue Coordination Centre Tripoli over the newly formalized Libyan Search and Rescue Region. It argues that the recognition of the Libyan coordination authority made by the International Maritime Organisation, has changed the way the international waters separating Libya and Europe are governed. Through the close analysis of three ethnographic vignettes depicting instances of rescue of migrants by an NGO vessel, this article illustrates how the Italian authorities are able to exercise control over this vast area indirectly via the formalization of the Libyan authority and concomitantly imped the operations of civil rescue NGO boats in the zone. This formalization enables Italian authorities (and their EU counterparts) to establish a form of indirect governance in this liminal border zone that clashes with other preceding legal orders which regulate distress cases at sea, i.e. international maritime law.

The United States Coast Guard (USCG) Great Lakes Icebreaking Capability Replacement Project (GLIB) is a major acquisition program chartered to maintain heavy icebreaking on the Great Lakes. The state-of-the-art icebreaker being constructed under this program will replace the USCGC MACKINAW (WAGB 83), which has provided 60 years of continuous service to the region. The new multi-purpose vessel will provide heavy icebreaking services and maintain floating Aids-to-Navigation (AtoN) on the Great Lakes. In addition, the vessel will have secondary mission objectives of search and rescue, marine environmental response, and maritime law enforcement.

AbstractThe paper presents the derivation of a new equivalent skin friction coefficient for estimating the parasitic drag of short-to-medium range fixed-wing unmanned aircraft. The new coefficient is derived from an aerodynamic analysis of ten different unmanned aircraft used for surveillance, reconnaissance, and search and rescue missions. The aircraft is simulated using a validated unsteady Reynolds-averaged Navier Stokes approach. The UAV’s parasitic drag is significantly influenced by the presence of miscellaneous components like fixed landing gears or electro-optical sensor turrets. These components are responsible for almost half of an unmanned aircraft’s total parasitic drag. The new equivalent skin friction coefficient accounts for these effects and is significantly higher compared to other aircraft categories. It is used to initially size an unmanned aircraft for a typical reconnaissance mission. The improved parasitic drag estimation yields a much heavier unmanned aircraft when compared to the sizing results using available drag data of manned aircraft.

We develop a decentralized hybrid controller for fixed-wing UAVs assisting a manned helicopter in a United States Coast Guard search and rescue mission. The UAVs assist the manned helicopter by providing an expanded sensor footprint using onboard cameras. We consider two UAVs, one flying on either side of the helicopter, with constant velocity and maximum turn rate constraints. Tracking the helicopter around sharp corners will be difficult due to these constraints and the difference in path lengths for the two UAVs. To solve this problem, we propose a hybrid controller that allows the UAVs to swap positions in an attempt to improve the tracking and ground coverage performance of the formation. We discuss tracking control, the position swapping algorithm and collision avoidance. Simulation results demonstrate improved search efficiency and aircraft safety.

The article analyses the accusations made by the press against the Frontex agency (The European Border and Coast Guard Agency – EBCG). Media investigations have revealed noncompliance with the norms of European and international law in the agency’s operations, including violations of migrants’ rights during maritime search and rescue operations: pushback of boats, abuse of authority during return of those who were refused asylum. The author presents the positions of the Council and the Commission, emphasizing that the activities and reputation of the EBCG are very important for the EU leadership, since the agency’s reform is one of the few points of the program document «Pact on Migration and Asylum» that does not cause objections from the Member States. The article also touches upon the issues of arming the agency’s personnel, which cannot be organized without a clear legal justification. While agreeing with the Commission’s assertion that the increased attention to Frontex’s activities is due to the prospects for expanding its powers, staff and funding, the author still concludes that the agency’s problems reflect the unsatisfactory state of the EU’s migration and asylum policy.
