This paper discusses the current and new satellite transponders for global tracking and detecting of oceangoing ships, assets, crew, passengers and any moving objects at sea for enhanced vessels traffic control and management. These transponders are able to monitor all maritime assets and to improve safety, security of movements and collision avoidance, especially during very bad weather conditions and visibility. By deployment of the Global Navigation Satellite System (GNSS) in integration with Inmarsat, Iridium and other satellite systems in one unit with antenna, it is possible to provide reliable positioning and tracking solutions for civilian maritime, other mobiles and personnel at different Radio Frequency (RF) bands. The existing and forthcoming space and ground segment for positioning and tracking solutions as a modern Satellite Asset Tracking (SAT) onboard ships, and other relating systems are discussed and benefits of these new technologies and solution for improved positioning and tracking are explored.

A method for identification and tracking of pollutants plumes in water is presented and applied to laboratory data. This method uses the intensity threshold and associated image processing algorithms to identify the pollutant’s plume within a footage. Quantitative geometrical parameters are then extracted on each frame as proxies of the turbulent diffusion (i.e. area and perimeter) and advection (i.e. centroid location). From the determined plume location in each frame, it is then possible to devise a tracking algorithm which can determine the trajectory and eventual fate of the plume. The developed method is applied to two different types of plumes: one generated by a liquid pollutant (rhodamine) and another by a granular matrix type material (coal) to compare its capability of tracking different plumes. Although developed with laboratory images, the presented method is general and can be applied to field images as well. The advantages and limitations of the proposed methodology are also discussed.

W artykule przedstawiono koncepcję i realizację sieci czujników zobrazowania w podczerwieni służącą do lokalizacji i śledzenia obiektów. Sieć czujników używa zespołu wielu miniaturowych mikrobolometrycznych kamer termowizyjnych o niskiej rozdzielczości (80 × 80 pikseli) do wykrywania, śledzenia i lokalizacji obiektów w obszarze obserwacji. Zastosowanie systemów termowizyjnych reagujących na promieniowanie podczerwone pochodzące z obiektów sprawia, że system jest odporny na warunki oświetlenia zewnętrznego i warunki środowiskowe. Jednocześnie zastosowanie czujnika podczerwieni wymaga zastosowania specjalnie zaprojektowanych, dedykowanych technik przetwarzania obrazu. W artykule opisano techniki przetwarzania obrazu, sposoby lokalizacji obiektów, pomiary dokładności, porównanie z innymi znanymi rozwiązaniami oraz wnioski końcowe.

This paper presents a concept and implementation of an infrared imaging sensor network for object localization and tracking. The sensor network uses multiple low-resolution (80× 80 pixels) microbolometric thermal cameras to detect, track and locate an object within the area of observation. The network uses information simultaneously acquired from multiple sensors to detect and extract additional information about object’s location. The use of thermal-imaging systems responsive to objects’ natural infrared radiation, makes the system resistant to external illumination and environmental conditions. At the same time, the use of infrared sensor requires application of specially designed, dedicated image processing techniques appropriate for this kind of sensor. The paper describes: image processing techniques, means of object localization, accuracy measurements, comparison to other known solutions and final conclusions.

The field of research of this paper combines Human Computer Interface, gesture recognition and fingertips tracking. Most gesture recognition algorithms processing color images are unable to locate folded fingers hidden inside hand contour. With use of hand landmarks detection and localization algorithm, processing directional images, the fingertips are tracked whether they are risen or folded inside the hand contour. The capabilities of the method, repeatibility and accuracy, are tested with use of 3 gestures that are recorded on the USB camera. Fingertips are tracked in gestures presenting a linear movement of an open hand, finger folding into fist and clenched fist movement. In conclusion, a discussion of accuracy in application to HCI is presented.

Target tracking is one of the most common research themes in Computer vision. Ideally, a tracking algorithm will only once receive information about the target to be tracked and will be fast enough to identify the target in the remaining frames, including when its location changes substantially from one frame to another. In addition, if the target disappears from the area of interest, the algorithm should be able to re-identify the desired target. Target tracking was done using a drone with a Jetson TX2 computer onboard. The program runs at the drone level without the need for data processing on another device. Cameras were attached to the drones using a gimbal that maintains a fixed shooting angle. Target tracking was accomplished by placing it in the centre of the image with the drone constantly adjusting to keep the target properly framed. To start tracking, a human operator must fit the target he wishes to follow in a frame. The functionality of this system is excellent for remote monitoring of targets.

This paper shows how the processing of track innovations data produced by the discrete Kalman Filter may be used to infer the actual measurement covariance matrix, in situations where the latter is poorly known. In addition to the familiar innovations formed from the difference of the measurement from the extrapolated state vector, it is beneﬁcial to compute a similar quantity from the updated track state and analyse the two quantities in combination.

High energy physics experiments require fast and efficient methods for reconstructing the tracks of charged particles. The commonly used algorithms are sequential and the required CPU power increases rapidly with the number of tracks. Neural networks can speed up the process due to their capability of modeling complex non-linear data dependencies and finding all tracks in parallel. In this paper, we describe the application of the deep neural network for reconstructing straight tracks in a toy two-dimensional model. It is planned to apply this method to the experimental data obtained by the MUonE experiment at CERN.

EDAS (EGNOS Data Access Service) is the EGNOS internet broadcast service, which provides free of charge access to the data collected and generated by the EGNOS infrastructure. EDAS disseminates over the Internet, both in real time and via an FTP archive, the raw data of the GPS, GLONASS (no commitment on GLONASS data is provided (1)) and EGNOS GEO satellites collected by the receivers located at the EGNOS reference stations, which are mainly distributed over Europe and North Africa. The EDAS services offer several types of GNSS data in various protocols and formats, such as DGNSS corrections. This paper reports on the results of some in-field tests conducted by ESSP and Topcon Agriculture to confirm the suitability of EDAS DGNSS corrections for precision farming in Europe. The European Commission (EC) is the owner of EGNOS system (including EDAS) and has delegated the exploitation of EGNOS to the European GNSS Agency (GSA). EDAS service provision is performed by ESSP, as EGNOS Services Provider, under contract with the GSA, the EGNOS program manager. In the ENC 2018 article “EDAS (EGNOS Data Access Service): Differential GPS corrections performance test with state-of-the-art precision agriculture system”, ESSP and Topcon Agriculture presented the results of the first in-field test conducted in a dynamic and real-life environment in the summer of 2017. The test results indicated that the EDAS DGNSS corrections could enable a reliable pass-to-pass accuracy performance for a wide range of precision agriculture applications and become an attractive solution for cereal farms, when the farm is located in the vicinity of an EGNOS reference station. In particular, Topcon Agriculture acknowledged that the observed performance was sufficient to support the following precision agriculture applications: spraying and spreading of any crop type, tilling and harvesting of cereal. Then, ESSP and Topcon Agriculture engaged in additional testing activities to further characterise the EDAS DGPS performance in different scenarios (i.e. at various European locations and with a variety of distances between the designated farm and the target EGNOS reference station). In each test, multiple runs with the rover tractors have been performed over the reference patterns predefined in the Topcon guidance systems. Data recorded during the tests has been analysed in detail, looking at the key performance indicators (e.g. cross track error and pass-to-pass performance) that characterize the EDAS DGPS performance for precision agriculture applications. Different techniques for the computation of the pass-to-pass accuracy performance have been used, including a procedure to measure live in the field and a post-processing alternative. The diversity of scenarios available allows drawing conclusions on the applicability of EDAS DGPS corrections (in terms of maximum distance from the target EGNOS station) for precision agriculture and also understanding the impact of operationally relevant aspects such as the quality of the mobile internet coverage (highly variable across Europe). The EDAS system and its architecture, the main types of data disseminated through EDAS services and the online information available to the EDAS users are introduced in this paper. In particular, the EDAS Ntrip service is described in detail, since it provides the differential corrections to the GPS and GLONASS satellites at the EGNOS reference stations in RTCM format, which are the basis for the present study. The article also reports on the results of the latest tests, which have been performed using Topcon receivers, vehicles and auto-steering systems. In all cases, two different Topcon guidance systems on board tractors were running simultaneously to assess the EDAS DGPS positioning performance with respect to a the reference provided by a top-performing RTK-based Topcon solution. The objective of this paper is to draw conclusions on the use of EDAS DGPS corrections as a reliable free-of-charge alternative for precision farming in Europe (especially for cereal farms), based on the available performance results from the testing campaign and the feedback from the involved precision agriculture experts.

Standard Guidance, Navigation, and Control (GN&C) systems take state data from a navigation system and create a trajectory that minimizes some a-priori determined cost function. These cost functions are typically time, money, weight, or any general physically realizable quantity. Previous work has been done to show the effectiveness of using risk as the sole objective function. However, this previous work used Poisson distributions and historical estimates to achieve this goal. In this paper we present the situation-risk assessment (SRA) method contained within the intelligent situation assessment and collision avoidance (iSC) platform. The SRA method uses data clustering, and pattern recognition to create a historically based estimate of guidance probabilities. These are then used in data driven, dynamic models to create the future probability fields of the situation. This probability, along with the other agent’s goals and objectives, are then used to create a minimum risk guidance solution in the nautical environment.

Even though satellite-based positioning increases rescue workers’ safety and efficiency, signal availability, reliability, and accuracy are often poor during fire operations, due to terrain formation, natural and structural obstacles or even the conditions of the operation. In central Europe, the stakeholders report a strong necessity to complement the location for mixed indoor-outdoor and GNSS blocked scenarios. As such, location information often needs to be augmented. For that, European Global Navigation Satellite System Galileo could help by improving the availability of the satellites with different features. Moreover, a multi-sensored collaborative system could also take advantage of the rescue personnel who are already involved in firefighting and complement the input data for positioning. The Autonomous Indoor & Outdoor Safety Tracking System (AIOSAT) is a multinational project founded through the Horizon 2020 program, with seven partners from Spain, Netherlands and Belgium. It is reaching the first year of progress (out of 3) and the overarching objective of AIOSAT system is to advance beyond the state of the art in tracking rescue workers by creating a high availability and high integrity team positioning and tracking system. On the system level approach, this goal is achieved by fusing the GNSS, EDAS/EGNOS, pedestrian dead reckoning and ultra-wide band ranging information, possibly augmented with map data. The system should be able to work both inside buildings and rural areas, which are the test cases defined by the final users involved in the consortium and the advisory board panel of the project.

In this paper, we analyze the acquisition and tracking performance of signal using a tiered differential polyphase code as the secondary code. The Zadoff-Chu sequence is known to have a CAZAC (Constant Amplitude Zero Auto-Correlation) characteristics. The secondary code generated by differential encoding of the Zadoff-Chu sequence also has the same characteristics as the Zadoff-Chu sequence. Therefore, long integration will give better correlation results. We compare signal acquisition and tracking performance when using the NH sequence and Zadoff-Chu sequence as the secondary code. Monte-carlo simulation is performed using MATLAB. We use the probability of detection and the mean acquisition time for signal acquisition performance and tracking jitter for signal tracking performance.

Badania przeprowadzono na dwóch najczęściej stosowanych typach mieszanki mineralno-asfaltowej, jakimi są: beton asfaltowy oraz SMA. Celem badań było sprawdzenie, w jakim stopniu wyniki testu koleinowania próbek walcowych będą się różnić od wyników otrzymanych na próbkach prostopadłościennych. Uzyskane wyniki badań wykazały, że w przypadku mieszanki mineralno-asfaltowej typu SMA wartość wyznaczonych parametrów (WTSAIR oraz PRDAIR) nie wykazuje istotnej różnicy bez względu na kształt badanej próbki. Dużo bardziej zróżnicowane są wyniki uzyskane na próbkach prostopadłościennych i walcowych z betonu asfaltowego.

The article presents a comparison of wheel tracking test results of HMA obtained by using samples of various shapes and sizes: prismatic and cylindrical with diameters of ø200 mm and ø250 mm. The tests were carried out for the two most commonly used types of HMA: asphalt concrete and SMA. The aim of the research was to check how much results of the rutting test conducted using cylindrical samples will differ from the results obtained for a prismatic sample. The obtained test results showed that in the case of the SMA specimens the differences in the determined parameters (WTSAIR and PRDAIR) are not significant regardless of the shape of the tested sample. Much bigger differences between results of the tests performed on prismatic and cylindrical samples were obtained in the case of asphalt concrete.

We analyze quadratic performance for switched systems which are composed of a finite set of affine time-varying subsystems, where both subsystem matrices and affine vectors are switched, and no single subsystem has desired quadratic performance. The quadratic performance indexes we deal with include stability, tracking and L2 gain. We show that if a linear convex combination of subsystem matrices is uniformly Hurwitz and another convex combination of affine vectors is zero, then we can design a state-dependent switching law (state feedback) and an output-dependent switching law (output feedback) such that the entire switched affine system is quadratically stable at the origin. In the case where the convex combination of affine vectors is nonzero, we show that the tracking control problem can be posed and solved using a similar switching strategy. Finally, we consider the L2 gain analysis problem for the switched affine time-varying systems under state feedback.

Guarantee of the ship safety is the primary task posed for modern navigation systems. This concerns monitoring the proper ship position as well as providing accurate information about the collision threat. The proper interpretation of this information belongs to the navigator. He must take into account many variables affecting the assessment of the situation and then make the right decision regarding anti-collision manoeuvres. This assessment could be made easier for him with use some form of graphic target data presentation methods other than currently required and described in IMO performance standards. Other possible graphic presentation methods of collision information are described in the article along with the concept of their usage.
