[Termes IGN] signal GNSSRésumé : (auteur) This thesis provides a comprehensive overview of all current and planned satellite navigation systems, either global or regional, putting special emphasis on their signal structure. Particular attention is paid to the European Global Navigation Satellite System Galileo, under development at the moment. The results of this work can be considered as a significant contribution to the design and development of the Galileo’s Open Service (OS) in the E1 frequency band. The present work provides as main contribution a generally valid theoretical framework with which all current and future navigation signals can be described. Generalized signal waveforms and their corresponding time and spectral characteristics are derived and investigated. Complete families of signals are presented and analyzed regarding their spectral and performance characteristics, underlining their potential for future generations of satellite navigation systems. This thesis proves that the generalized signal waveforms proposed in this work cover any current and other optimized signals that could be proposed in the future. In this sense, it is shown that all current navigation signals can be mathematically described as Multilevel Coded spreading Symbols or, in particular, as Binary Coded Symbols. Using the analytical expressions of the generalized signal model, the corresponding generalized signal waveforms are further studied regarding their Spectral Separation Coefficients (SSCs). This parameter is of great interest in satellite navigation to understand the compatibility between different signals. Generalized formulas for smooth spectra are also derived to calculate the SSCs between any two arbitrary signals. Particular cases of interest are computed following the obtained analytical expressions and by means of simulations with real Pseudo Random Noise (PRN) codes. Results from this comparison show a perfect matching between the predicted analytical results and the numerical computations. Realistic scenarios are carried out to assess the impact of non-ideal PRN codes and navigation data onto the spectral properties that have been derived analytically. Finally, current and new multiplexing schemes are studied in detail together with the feasibility to introduce optimized signal waveforms. Special attention is paid to understand the required changes that are necessary to multiplex non-binary signals. Pros and Cons of the different solutions are discussed and investigated with regard to the application of future signal waveforms. Among these last ones, the Composite Binary Offset Carrier (CBOC) implementation of the Multiplexed Binary Offset Carrier (MBOC) modulation for the Galileo’s Open Service signal in the E1 frequency band deserves an important chapter. In addition, some chapters are dedicated to analyze receiver structures optimized to work with MBOC for both GPS and Galileo. Note de contenu : 1. Introduction

More and more technical professionals are entering the field and looking for practical, up-to-date engineering know-how. This single-source reference answers the call, providing both an introduction to overall systems operation and an in-depth treatment of architecture, design, and component integration. The book explains how satellite, on-board, and other navigation technologies operate, and it gives practitioners insight into performance issues such as processing chains and error sources. Providing solutions to systems designers and engineers, the book describes and compares different integration architectures, and explains how to diagnose errors. Moreover, this hands-on book includes appendices filled with terminology and equations for quick referencing. Note de contenu : Introduction

[Termes IGN] SuisseRésumé : (Auteur) Le délai troposphérique inhérent aux signaux GPS a des répercussions négatives sur la précision du positionnement. Toutefois, il peut aussi fournir des renseignements sur l’état de la troposphère, qui peuvent être utiles pour de nombreuses applications météorologiques. Avec un réseau permanent de récepteurs GPS et en utilisant les délais humides en pente (DHP) entre les récepteurs et les satellites, il est possible d’élaborer un modèle 3D pour la réfractivité humide à l’intérieur du réseau. À cette fin, nous proposons l’utilisation d’un développement en série 3D de Taylor. Pour faire l’essai de cette approche, on a utilisé un réseau permanent de 43 stations GPS en Suisse pour évaluer les DHP. Ensuite, ces valeurs ont servi de données d’intrant pour le modèle proposé. L’utilisation de ce modèle permet d’évaluer le délai humide zénithal (DHZ) pour un emplacement 3D aléatoire à l’intérieur du réseau. Le DHZ qui en découle peut ensuite être utilisé pour corriger les délais troposphériques de tout récepteur GPS itinérant supplémentaire qui ne fait pas partie du réseau. On a validé les valeurs humides de réfractivité obtenues du modèle avec les données météorologiques rassemblées à des stations météorologiques indépendantes en Suisse.

[Termes IGN] résiduRésumé : (auteur) For the first time, the ITRF2005 input data are in the form of time series of station positions and Earth orientation parameters, together with full variance-covariance information. The first step of the ITRF2005 analysis consists of rigorously stacking each time series to yield a long-term solution per technique. As a by-product, time series of position residuals contain the nonlinear motion of points over the Earth's surface. In this paper, the height residual time series of very long baseline interferometry (VLBI), Global Positioning System (GPS), and satellite laser ranging (SLR) solutions submitted to ITRF2005 are compared. We note that the interpretation of the ITRF2005 position residual time series as observed physical motions at the various stations is delicate due to the inhomogeneous site distribution. We estimate that the network effect may introduce an averaged scatter of 3 and 2 mm in the VLBI and SLR height residuals, respectively. Although noise levels are different among these three techniques, a common 1.0 cycles per year (cpy) frequency is clearly detected. The GPS height annual signal exhibits significant regional correlations that are confirmed by VLBI and SLR measurements in some colocated sites. Significant power near frequencies 2.00, 3.12, and 4.16 cpy is also detected in the individual GPS height residuals time series as mentioned by Ray et al. (2007). However, neither VLBI nor SLR show any significant signals at these frequencies for colocated sites. The agreement between detrended height time series at colocated sites is quantified using a novel method based on Kalman filtering and on maximum likelihood estimation. The GPS and VLBI measurements are shown to agree fairly well for most of the colocated sites. However, agreement is not generally observed in the GPS and SLR comparisons. A study of the interannual signal at colocated sites indicates that the good correlation cannot be completely attributed to the annual harmonic.

[Termes IGN] test de performanceRésumé : (Editeur) GATE (Galileo Test Environment) is the only Galileo test and development environment worldwide where already today navigation is possible with realistic Galileo Signals on all frequencies in an outdoor area. Six transmissions stations deployed on top of six mountains in the German Alps, and two monitoring stations in the valley are the components making GATE a unique test environment. Receivers and applications being operated on the test ground receive the transmitted signals in such a way as if they were radiated from real Galileo satellites in the earth orbit. Thus, GATE enables an early development of technologies, receivers, applications and services, which will decisively influence the navigation market and so fosters the development in nearly all fields of Galileo products.
