Abstract:
For the last two decades, the American GPS and Russian GLONASS were the basic systems used in global positioning and navigation. In recent years, there has been significant progress in the development of positioning systems. New regional systems have been created, i.e., the Japanese Quasi-Zenith Satellite System (QZSS) and Indian Regional Navigational Satellite System (IRNSS). A plan to build its own regional navigation system named Korean Positioning System (KPS) was announced South Korea on 5 February 2018. Currently, two new global navigation systems are under development: the European Galileo and the Chinese BeiDou. The full operability of both systems by 2020 is planned. The paper deals with a possibility of determination of the user’s position from individual and independent global navigation satellite system (GNSS). The article is a broader concept aimed at independent determination of precise position from individual GPS, GLONASS, BeiDou and Galileo systems. It presents real time positioning results (Real Time Kinematic-RTK) using signals from Galileo satellites only. During the test, 14 Galileo satellites were used and the number of simultaneously observed Galileo satellites varied from five to seven. Real-time measurements were only possible in certain 24-h observation windows. However, their number was completed within 6 days at the end of 2017 and beginning of 2018, so there was possible to infer about the current availability, continuity, convergence time and accuracy of the RTK measurements. In addition, the systematic errors were demonstrated for the Galileo system.

Abstract:
With the existing GPS, the replenishment of GLONASS and the launching of Galileo there will be three satellite navigation systems in the future, with a total of more than 80 satellites. So it can be expected that the performance of the global navigation satellite system (GNSS) will be greatly improved, especially in urban environments. This paper studies the potential benefits of GPS/GLONASS/Galileo integration in an urban canyon – Hong Kong. The navigation performances of four choices (GPS alone, GPS+GLONASS, GPS+Galileo and GPS+GLONASS+Galileo) are evaluated in terms of availability, coverage, and continuity based on simulation. The results show that there are significant improvements in availability, coverage and continuity, by using GPS+GLONASS+Galileo compared with the other choices. But the performance is still not good enough for most navigation applications in urban environments.

Abstract:
This, and the following three papers, where first presented at GNSS 99, the Second European Symposium on Global Navigation Satellite Systems held in Genoa, Italy from 5th to 8th October 1999.Galileo is being developed as the European contribution to the next generation of navigation satellites to replace GNSS1. Sponsored by the European Union, Galileo will be a civil, internationally controlled and operated system that will secure the long-term availability of satellite-based navigation services for multi-modal purposes throughout the European region and beyond. Galileo will be designed to support a wide variety of applications. These include professional navigation, position reference, safety, emergency, tracking, sport/leisure and governmental. Such services may be open to all, for safety-of-life applications, or for commercial users. In the case of safety and commercial applications in particular, it is imperative that the appropriate institutional control and regulatory framework is in place for purposes of safety and economic regulation. To ensure that the various parties understand their obligations and liabilities, clear legal instruments must be put in place to support the organisational framework. It is planned to attract private investment to fund elements of system development and operation through Private/Public Partnership arrangements. At present there is no institutional, regulatory or legal framework that will enable the early impetus to Galileo development to be maintained. This presents a challenge that Europe must address without delay. It has been the subject of several European Commission studies in the past twelve months. In a complementary activity under contract to the European Space Agency (ESA), a European industry consortium comprising Alcatel, Alenia, DASA and Matra Marconi Space was tasked to complete the preliminary design of the space and ground segments by the Autumn of 1999. One task of this study, led by Matra Marconi Space, relates to a study of the impact of institutional, regulatory and legal issues on the organisation and development of Galileo. This paper describes the studies undertaken into these issues within the overall Galileo development programme.

Abstract:
The tropospheric delays estimated from the Global Navigation Satellite System (GNSS) have been proven to be an efficient product for monitoring variations of water vapor, which plays an important role in meteorology applications. The operational GNSS water vapor monitoring system is currently based on the Global Positioning System (GPS) and GLObal NAvigation Satellite System(GLONASS) dual-frequency observations. The Galileo satellite navigation system has been evolving continuously, and on 11 February 2019, the constellation reached 22 active satellites, achieving a capability of standalone Precise Point Positioning (PPP) and tropospheric estimation that is global in scope. This enhancement shows a 37% improvement if the precision of the Galileo-only zenith tropospheric delay, while we may anticipate further benefits in terms of tropospheric gradients and slant delays in the future if an optimal multi-constellation and multi-frequency processing strategy is used. First, we analyze the performance of the multi-frequency troposphere estimates based on the PPP raw observation model by comparing it with the standard ionosphere-free model. The performance of the Galileo-only tropospheric solution is then validated with respect to GPS-only solution using 48 globally distributed Multi-GNSS Experiment (MGEX) stations. The averaged bias and standard deviations are −0.3 and 5.8 mm when only using GPS satellites, respectively, and 0.0 and 6.2 mm for Galileo, respectively, when compared to the International GNSS Service (IGS) final Zenith Troposphere Delay(ZTD) products. Using receiver antenna phase center corrections from the corresponding GPS dual-frequency observations does not affect the Galileo PPP ambiguity float troposphere solutions. These results demonstrate a comparable precision achieved for both Galileo-only and GPS-only ZTD solutions, however, horizontal tropospheric gradients, estimated from standalone GPS and Galileo solutions, still show larger discrepancies, mainly due to their being less Galileo satellites than GPS satellites. Including Galileo E1, E5a, E5b, and E5 signals, along with their proper observation weighting, show the benefit of multi-frequency observations, further improving the ZTD precision by 4% when compared to the dual-frequency raw observation model. Overall, the presented results demonstrate good prospects for the application of multi-frequency Galileo observations for the tropospheric parameter estimates.

Abstract:
User range error (URE) is widely used to measure the effects of satellite orbit error and clock error on user positioning. A detailed calculation method of URE was brought forward including the partitions of the ground coverage of the MEO satellites and the calculation methods of the projection parameters of URE. The different URE performance of multiple Satellite navigation system was analyzed. Simulation results show that the radial direction projection parameters are basically the same, but the horizontal direction projection parameters are different among GPS, Galileo and BDS. The higher the satellite orbit, the smaller the horizontal direction projection parameters.

Abstract:
The study includes the description of development conditions for the satellite navigation programme Galileo. Its also includes some aspects of the Galileo programme accomplishment, especially its influence on the integration process in Europe and tightening the international connections. The programme has been implemented since the 1990s and its aim is to ensure the independence of the EU countries in such sectors of their economy which are based on the precise information related to location and time. Galileo has also its overregional dimension, which is the result of satellite constellation and its global reach. It is the biggest industrial project conducted within the integrated European structures. What is more, the distinction of Galileo among other European satellite programmes has its roots in its crucial strategic significance rather than in technology or investment costs. So far, the cosmologic institutions have not been formally connected with the integrated European structures, and less importance has been attached to political aspects of their projects. The transformation of the Galileo programme is proceeding in the condition of potential incomes risk from the system work. The fiasco of public and private partnership establishments was the result of differences in estimating the risk of trade incomes and market development. In 2013 Galileo will be in its full operation process and first GPS III satellites will work, what is more, the high precision of this American system and other integrated GNSS systems will establish competition in terms of commercial and amateur aplications. Widening the cooperation between the EU countries and the USA implies many positive effects, such as creating the idea of a multi-system satellite scheme, the compatibility of Galileo and GPS receivers and, what follows, the increase of navigation precision and reduction of overall costs borne by the system owners.

Abstract:
The law of global navigation satellite systems is a nascent, yet growing academic field. The subject matter it studies, GNSS, has been and is becoming ever-more important in the modern world, both for transportation, as well as for commerce. Indeed, globalization has seen billions of euros in trade associated with both nautical and aviation shipping, and this trend is likely to grow larger with the passage of time. Additionally, the nations of the world are fast realizing the potential of GNSS to make their aviation industries more robust and efficient, with integration of GNSS into air traffic management certain to increase the number of aircraft in flight at any given time, decrease the separation between such craft, and allow for safer takeoffs and landings, as well as improve flight in areas whose terrain has traditionally been quite challenging for contemporary navigational aids. In 2004, the United States and the European Community signed an Agreement intended to ensure radio compatibility and interoperability between the U.S. Global Positioning System and the upcoming Galileo GNSS. This collaboration should enable continued and rapid growth of commerce and navigation improvements to aviation, but several of its provisions are poorly, if at all, defined. As a result, this thesis attempts to elaborate the nature and meaning behind the 2004 Agreement, while also serving to illuminate current legal theories concerning the liability regimes that accompany GNSS.<br>Le droit des systèmes de positionnement par satellites (GNSS) est une nouvelle matière académique qui est en train de se développer. Le GNSS devient de plus en plus important dans le monde d'aujourd'hui tant pour le transport que pour le commerce. La mondialisation a contribué à la croissance du transport des biens par voies maritime et aérienne, et cette tendance ne pourrait qu'augmenter. Les pays du monde se rendent de plus en plus compte des possibilités d'usage du GNSS pour renforcer leurs industries aériennes en employant le GNSS dans la gestion du trafic aérien afin d'augmenter la capacité du ciel en réduisant la distance séparant les aéronefs, de rendre plus sécuritaires les décollages et les atterrissages, et de faciliter l'aviation dans des zones où la technologie contemporaine a prouvé insuffisante. En 2004, les États-Unis et l'Union Européenne ont signé un accord qui assure la radio-compatibilité et l'interopérabilité du système GNSS américain et son équivalent européen, Galileo. Cette collaboration devrait contribuer à une croissance continue du commerce et de l'aviation. Par contre, plusieurs dispositions dans l'accord sont mal ou pas du tout définies. Cette mémoire cherche donc à élaborer la nature ainsi que le sens à donner à l'accord de 2004, tout en exposant les théories juridiques contemporaines concernant la responsabilité juridique pour GNSS.

Abstract:
In 1999 Europe, through the European Commission and the European Space Agency, began detailed definition of a second generation Global Navigation Satellite System (GNSS). This GNSS development programme, known as “Galileo”, was intended to both complement and compete against the existing US Global Positioning System (GPS). Unlike GPS, Galileo is intended to be privately financed, following the initial development investment from the EC and ESA, which implies that Galileo should provide some revenue-earning services. From its earliest inception, the basis of these services has been assumed to be through the provision of Signal Integrity through an Integrity Flag broadcast through the Galileo system– a service which GPS cannot provide without some external system augmentation. This thesis undertakes a critical evaluation of the value of this integrity system in Galileo. This thesis has two parts. The first demonstrates that the conditions required to attract adequate private finance to the Galileo programme are incompatible with the system architecture derived from the early Galileo system studies and taken forward into the system early deployment phase, which includes an Integrity system within Galileo. The second part of this thesis aims to demonstrate that receivers which can combine the signals from GPS and Galileo may offer a free Integrity service which meet the needs of the majority of users, possibly up to the standards required for aviation precision approach. A novel Receiver Autonomous Integrity Monitoring (RAIM) technique is described, using an Errors in Variables/Total Least Squares approach to the detection of inconsistencies in an over-determined set of GNSS signal measurements. The mathematical basis for this technique is presented, along with results which compare the simulated performance of receivers using this algorithm against the expected performance of Galileo’s internal integrity determination system.

Abstract:
La propagation des ondes électromagnétiques dans l’ionosphère est influencée par le nombre d’électrons libres présent le long du trajet de propagation, représenté par le contenu électronique total (CET). La conception des signaux GPS, basée sur l’utilisation de deux fréquences porteuses, permet de corriger l’erreur ionosphérique au premier ordre, ce qui conduit à une élimination de plus de 99% du retard ionosphérique. Dans une première partie de ce travail on montre que pour des applications où une précision plus importante est attendue, l’élimination des ordres supérieurs s’avère nécessaire, car ils peuvent induire une erreur de plusieurs centimètres sur l’estimation de la distance satellite-récepteur. Pour diminuer cette erreur, on propose un modèle de correction, applicable aux systèmes bi-fréquence actuels ainsi qu’aux futurs systèmes tri-fréquence. Dans une deuxième partie du travail, on analyse l’utilisation de trois fréquences pour le système GPS et le futur système Galileo, ainsi que la précision des codes de ce dernier. Les premiers résultats obtenus à partir des mesures des signaux Giove-A montrent que le bruit de mesure d’un système tri-fréquence ne permet pas l’estimation en temps réel de l’effet des termes d’ordre supérieur. La correction de ces termes doit donc s’effectuer par l’utilisation d’un modèle. Finalement, on réalise une évaluation des effets de la correction du terme ionosphérique du deuxième ordre en suivant une stratégie basée sur le Positionnement Ponctuel Précis (PPP) en configuration mono-station ainsi qu’une autre stratégie basée sur le traitement GPS en réseau. Les différences observées sur l’estimation de la position et sur le retard troposphérique sont abordées de façon approfondie lors de perturbations ionosphériques présentant de forts CET. Une interprétation des résultats est présentée en fonction de la stratégie utilisée pour l’obtention de la solution en réseau<br>Electromagnetic wave propagation in the ionosphere is influenced by the number of free electrons present along the propagation path and represented by the Total Electron Content (TEC). GPS signals based on the use of two carrier frequencies enable one to reduce the ionospheric error to the first order, which implies an elimination of more than 99% of the ionospheric delay. Firstly we show in this work that for applications in which better precision is awaited, the elimination of higher order; proves to be necessary, because they can induce an error of several centimeters. To mitigate this error, we propose a correction model, applicable to current dual frequency systems as well as to triple frequency systems. Secondly, we analyze the use of three frequencies for the future GPS and Galileo systems, as well as the precision of the codes of the last one. First results obtained from Giove-A signals measurements show that the estimate of higher ionospheric terms is not possible in real time in a triple-frequency system due to the measurement noise. The model correction of the higher order terms is thus still appropriate. Finally, we evaluate the effects of the second-order term correction considering both Precise Point Positioning (PPP) in a single-station configuration and in the processing of data from a network of GPS receivers. In all cases we have taken into consideration ionospheric storm situations presenting very strong TEC values. Observed differences on position and tropospheric delay are carefully analyzed and the results are interpreted according to the strategy adopted for the processing of network data

Abstract:
Abstract Global navigation satellite systems (GNSSs) have been widely used in navigation, positioning, and timing. China’s BeiDou Navigation Satellite System (BDS) would reach full operational capability with 24 Medium Earth Orbit (MEO), 3 Geosynchronous Equatorial Orbit (GEO) and 3 Inclined Geosynchronous Satellite Orbit (IGSO) satellites by 2020 and would be an important technology for the construction of Digital Earth. This chapter overviews the system structure, signals and service performance of BDS, Global Positioning System (GPS), Navigatsionnaya Sputnikovaya Sistema (GLONASS) and Galileo Navigation Satellite System (Galileo) system. Using a single GNSS, positions with an error of ~ 10 m can be obtained. To enhance the positioning accuracy, various differential techniques have been developed, and GNSS augmentation systems have been established. The typical augmentation systems, e.g., the Wide Area Augmentation System (WAAS), the European Geostationary Navigation Overlay Service (EGNOS), the global differential GPS (GDGPS) system, are introduced in detail. The applications of GNSS technology and augmentation systems for space-time geodetic datum, high-precision positioning and location-based services (LBS) are summarized, providing a reference for GNSS engineers and users.

Abstract:
For many years American GPS and Russian GLONNAS were the leading navigation systems widely used for navigation purposes. In recent years two new navigational systems have been developed. These systems are the European Galileo system and the Chinese BeiDou System. The full operability of both systems is foreseen for 2020. The full Galileo constellation will consist of 30 Medium Earth Orbit (MEO) satellites. In this paper the GPS and Galileo combination is used to obtain precise positions using the MAFA method. Results from GPS only and GPS+Galileo positioning are presented. In the test 11 Galileo satellites were used. The number of visible GPS satellites during the test was between 8 and 12. For Galileo the number of visible satellites was between 2 to 4, with 4 satellites visible for most of the day. Adding Galileo satellites to GPS reduces the PDOP factor value and improves the DGNSS and RTK results.

Abstract:
While Global Navigation Satellite Systems (GNSS) serve as a fundamental positioning technology for autonomous ships in Inland Waterways (IWW), in order to compensate for unexpected signal outages from constellations due to structures such as bridges and high buildings, it is not uncommon to use a sensor fusion setup with GNSS and Inertial Measurement Units (IMU)/Inertial Navigation Systems (INS). However, the accuracy of this fusion relies on the accuracy of the main localization technology itself. In Europe, Galileo and the European Geostationary Navigation Overlay Service (EGNOS) are two satellite navigation systems under civil control and they provide European users with independent access to a reliable positioning satellite signal, claiming better accuracy than what is offered by other accessible systems. Therefore, considering the potential utilization of these systems for autonomous navigation, in this paper, we discuss the results of a case study for benchmarking the accuracy of Galileo and EGNOS in IWW. We used a Coordinate Measurement Machine (CMM) and a sub-cm Real-Time Kinematic (RTK) service which is available in Flanders to quantify the benchmark reference. The results with and without sensor fusion show that Galileo has a better horizontal accuracy profile than standalone Global Positioning System (GPS), and its augmentation with EGNOS is likely to provide European IWW users more accurate positioning levels in the future.

Full text
Abstract:
Imagery collected via Unmanned Aerial System (UAS) platforms has become popular in recent years due to improvements in a Digital Single-Lens Reflex (DSLR) camera (centimeter and sub-centimeter), lower operation costs as compared to human piloted aircraft, and the ability to collect data over areas with limited ground access. Many different application (e.g., forestry, agriculture, geology, archaeology) are already using and utilizing the advantages of UAS data. Although, there are numerous UAS image processing workflows, for each application the approach can be different. In this study, we developed a processing workflow of UAS imagery collected in a dense forest (e.g., coniferous/deciduous forest and contiguous wetlands) area allowing users to process large datasets with acceptable mosaicking and georeferencing errors. Imagery was acquired with near-infrared (NIR) and red, green, blue (RGB) cameras with no ground control points. Image quality of two different UAS collection platforms were observed. Agisoft Metashape, a photogrammetric suite, which uses SfM (Structure from Motion) techniques, was used to process the imagery. The results showed that an UAS having a consumer grade Global Navigation Satellite System (GNSS) onboard had better image alignment than an UAS with lower quality GNSS.

Abstract:
With the advent of modern sensing technology, mapping products have begun to achieve an unprecedented precision of measurement. Considering their diverse use cases, several factors play a role in what would make the resulting measurements accurate. For light detection and ranging (LiDAR) and photogrammetry-based mapping solutions that implement vehicles outfitted with laser ranging devices, RGB cameras, and global navigation satellite system/inertial navigation system (GNSS/INS) georeferencing units, the quality of the derived mapping products is governed by the combined accuracy of the various sensors. While ranging errors associated with LiDAR systems or the imaging quality of RGB cameras are sensor-dependent and are mostly constant, the accuracy of a georeferencing unit depends on a variety of extrinsic factors, including but not limited to, availability of clear line-of-path to GNSS satellites and presence of radio interferences. The quality of the GNSS signal, in turn, is affected by the grade of hardware components used and, to a great extent, obstructions to signal reception. This document reports some of the major challenges of vehicle-based mobile mapping with regards to GNSS/INS navigation. The background of GNSS/INS positioning is discussed to build a framework for trajectory enhancement as well as improvement of LiDAR mapping products. The focus is put on using available sensor data from LiDAR and/or cameras to enhance their position/orientation quality. Some best practices in light of potential trajectory deterioration are also recommended.
