Повний текст джерелаThe provision of accurate positioning is becoming essential to our modern society. One of the main reasons is the great success and ease of use of Global Navigation Satellite Systems (GNSSs), which has led to an unprecedented amount of GNSS-based applications. In particular, the current trend shows that a new era of GNSS-based applications and services is emerging. These applications are the so-called critical applications, in which the physical safety of users may be in danger due to a miss-performance of the system. These applications have stringent requirements in terms of integrity, which is a measure of reliability and trust that can be placed on the information provided by the system. Unfortunately, GNSS-based critical applications are usually associated with terrestrial environments and original integrity algorithms usually fail. The main impairments are due to local effects such as interference, multipath or spoofing, which are assumed to be controlled in civil aviation but they are not in terrestrial environments. Thus, a new methodology for integrity is necessary in order to detect local effects and provide the additional level of integrity needed for GNSS-based critical applications; the so-called signal-level integrity. This thesis investigates novel detection algorithms with the aim of providing a new generation of integrity techniques in GNSS. For this purpose, the framework of Statistical Change Detection (SCD) is considered. This framework is of particular interest because its optimal criterion target the temporal dimension. This is an indispensable requirement for critical applications, in which a prompt detection is necessary. Therefore, the first part of this dissertation deals with the study of the field of SCD, including both Quickest Change Detection (QCD) and Transient Change Detection (TCD). Novel contributions are provided in the field of TCD, including the finite moving average solution and its statistical characterization. Numerical results show the superiority of our contributions. Finally, to conclude our study of SCD we compare it with classical detection schemes under the same mathematical framework. This comparison shows the appropriateness of SCD when dealing with timely detections. The main contribution of this thesis is the application of the SCD framework to threat detection and integrity in GNSS. To this end, we first investigate several properties of the received GNSS signal that may be useful for local threat detection. This leads us to move a step forward in the field of threat detection by proposing a novel QCD-based framework. Nonetheless, for integrity purposes a bounded delay is desirable, and it is here where TCD is of interest. For this reason, a novel TCD-based framework is considered for both multipath detection and integrity algorithms in GNSS, thus leading to the provision of signal-level integrity. A notable improvement is shown by the proposed TCD-based solutions considered in this thesis with respect to current solutions. In the last part of the thesis, the goal is to validate the proposed threat detectors and signal-level integrity algorithm using real GNSS signals. Real signal gathered in the context of an EC-funded research project is processed to show and validate the results of the implemented detectors. The results obtained in a realistic scenario show the improvement of the accuracy and integrity by using the proposed solution for signal-level integrity, with respect to current integrity algorithms. Furthermore, the proposed solution is shown to have real-time processing capabilities, thus being very attractive to improve current integrity algorithms and easily implementable in mass-market receivers.

Повний текст джерелаSatellite navigation (GNSS) is a constant in our days. The number of applications that depend on it is already remarkable and is constantly increasing. With new applications, new challenges have also risen: much of the new demand for signals comes from urban areas where GNSS signal processing is highly complex. In this thesis the issue of weak GNSS signal processing is addressed, in particular at the first phase of the receiver processing, known as signal acquisition. The first axe of research pursued deals with the analysis and compensation of the Doppler effect in acquisition. The Doppler shift that is experienced by a user is one of the main design drivers for the acquisitionmodule and solutions are proposed to improve the sensitivity-complexity trade-off typical of the acquisition process. The second axe of research deals with the characterization of differential GNSS detectors. After a first step of coherent integration, transition to post coherent (noncoherent or differential) integration is required for acquiring weak signals. The quantification of the sensitivity of differential detectors was not found in literature and is the objective of this part of the research. Finally, the third axe of research is devoted to multi-constellation Collective Detection (CD). CD is an innovative approach for the simultaneous processing of all signals in view. Severalissues related to CD are addressed, including the improvement of the CD search process and the hybridization with standard acquisition. Finally, the application of this methodology in the context of a multi-constellation receiver is also addressed, by processing simultaneously real GPS and Galileo signals

Повний текст джерелаGlobal Navigation Satellite Systems (GNSSs) have become an indispensable tool of daily life, since they offer us the possibility of accurately knowing our location in real time and in open-sky environments. Since the advent of these systems, a large number of successful GNSS applications have emerged. Some examples of these applications are: car navigation, flight tracking, sport activity tracking and augmented reality games. Due to the success achieved by GNSS, a great interest is emerging to extend its services to harsher environments such as urban canyons and indoor scenarios. However, in these environments GNSS receivers face great difficulties to detect the signals received from the satellites, which are very weak since they suffer from severe attenuation due to the presence of obstacles in the propagation path between satellites and the receiver. This thesis addresses several problems of processing weak GNSS signals, such as the detection at the acquisition stage, the determination of their signal quality and the time delay and Doppler frequency estimations. To do so, detection and estimation tools are used, which are based on the probability theory and statistics. In order to use these tools, it is necessary to understand the architecture and the signals that GNSSs transmit. For this reason, the first part of the thesis focuses on describing the main features of two of the best-known GNSSs, the American GPS and the European Galileo. In addition, we describe the fundamentals of the receivers and analyze the signals that are implemented in these systems. After that, we explain the required fundamentals of detection theory, namely the Neyman-pearson criterion, the Generalized Likelihood Ratio Test and the Bayesian approach. Then, a review of the state of the art in the detection of GNSS signals is carried out. The main contribution of this thesis is provided in the second part, which tackles the problem of deriving optimal detectors to acquire weak GNSS signals. We have found that the optimal detector depends on the characteristics of the signal transmitted by the satellite, which is different depending on the selected constellation. The theoretical and simulated results show that the detectors proposed in this thesis clearly outperform the detectors currently used in practice. In addition, we conclude when it is better to apply each detector. Moreover, this thesis addresses the problem of estimating the carrier-to-noise ratio of weak GNSS signals. This parameter provides essential information since it is used in all stages of GNSS receivers. In this thesis, we propose new estimators of the carrier-to-noise ratio, which are very simple to implement in high-sensitivity GNSS receivers and offer an enhanced accuracy with respect to the estimators proposed in the literature. Finally, the last part of the thesis focuses on the so-called high-order binary offset carrier (BOC) signals, a kind of signal that is implemented in the Galileo system. More precisely, this part is devoted to proposing accurate estimators of time delay and Doppler frequency. These estimators improve the accuracy of the method usually applied in practice to estimate these parameters.
