The effective requirements of the International Civil Aviation Organization (ICAO) for accuracy and reliability of aircraft (AC) positioning, especially in case of flights in the airfield area, make it particularly relevant to harmonize the accuracy characteristics of various radio systems so that any of them can be utilized during the flight. AC positioning accuracy amounts to several metres for standard GNSS modes or several centimetres for differential modes. At the same time, positioning errors for traditional short-range navigation and landing systems (VOR/DME, SHORAN or ILS), especially

Abstract. The presence of a wind turbine (WT) has the potential to distort electromagnetic fields emitted by terrestrial radio navigation aids. In this paper especially the field distortion of a Doppler Very High Frequency Omnidirectional Radio Range (DVOR) surveillance navigation system is investigated as a function of wind direction and rotor position. Therefor, the field distribution of a DVOR is simulated in the surrounding of a WT for 104 combinations of the angles of wind direction and rotor position. Furthermore, these calculations are executed for two different rotor diameters and 10 s

The article deals with the issues of determining the position of unmanned vehicles (UV) in tunnels in the absence of signals from global navigation satellite systems (GNSS) and unfavorable operating conditions, such as low light, high humidity, radioactivity and others. The authors proposes a method for navigating unmanned vehicles based on the phenomenon of electromagnetic induction. On board the unmanned vehicle there is a high-frequency generator, a radio transmitting unit, a radio receiving unit, an information management system, and under the bearing or supporting surface of the unmanned

AbstractToday, electromagnetic waves are the basic medium for all communication tasks. This applies also to navigation, where the most commonly waves have lengths measured in centimetres (radar, GPS) and longer, such as the waves used in the AIS or DGPS technologies. Navigators are mostly interested in the communication functionality of the used systems, i.e. such factors as range of the system and signal-to-noise ratio. This leads directly to increasing the transmitters’ power. However, it is important to bear in mind that the electromagnetic field can endanger human health, therefore, establ

Today, no single technology has more broad-reaching potential for worldwide civil aviation than the future applications of satellite technology. These applications represent the greatest opportunity to enhance aviation system capacity, efficiency and safety since the introduction of radio-based navigation systems more than 50 years ago. The foundation for this optimism is the Global Positioning System (GPS), a satellite-based radio navigation system operated and controlled by the United States Department of Defense (DoD). In December 1993, DoD declared GPS to be in initial operational capabili

The construction of fish passes has been a longstanding measure to improve river ecosystem status by ensuring the passability of weirs, dams and other in- channel structures for migratory fish. Many fish passes have a low biological effectiveness because of unsuitable hydrodynamic conditions hindering fish to rapidly detect the pass entrance. There has been a need for techniques to quantify the hydrodynamics surrounding fish pass entrances in order to identify those passes that require enhancement and to improve the design of new passes.

Radio frequency catheter ablation (RFCA) of cardiac arrhythmia is commonly performed by navigating the catheter manually. Nevertheless, remote navigation tech- niques where catheter steering is performed using either a magnetic field or robotically are available. Clinical ex- perience with these techniques demonstrated that higher contact forces can be achieved with robotic compared to magnetic field navigation [1]. This translates into more effective ablation lesions, but if excessive contact force is applied it may lead to higher risk of cardiac perforation [2]. However, the robotic navigati

Adaptive navigation is the process by which a vehicle determines where to go based on information received while moving through the field of interest. Adaptive sampling is a specific form of this in which that information is environmental data sampled by the robot. This may be beneficial in order to save time/energy compared to a conventional navigation strategy in which the entire field is traversed. Our work in this area focuses on multi-robot gradient-based techniques for the adaptive sampling of a scalar field. To date, we have experimentally demonstrated multi-robot gradient ascent/descen
