Car navigation is a field in broad expansion and the industry quickly developed a standard to model cartographic data useful for the applications of the road transport telematics: GDF, Geographic Data Files. Since its first version in 1988, GDF became an ISO standard in 2004, written by the technical committee TC 204. Consequently, the providers of data for navigation (Tele Atlas and Navteq) improved the content of their cartographic products by covering the road networks of the most part of the countries.

The diversity of road applications and intelligent transportation systems (ITS) makes the definition of positioning integrity a real challenge because the requirements are changing from one application to another. Even within liability or safety critical applications, the role of positioning may vary if the application layer requires a position at specific location (e.g. emergency call) or a series of positions along a vehicle’s trajectory (e.g. transport of dangerous goods). -- This paper is focusing on th

Cet article présente le développement et l'implémentation d'algorithmes permettant l'accès à une base de données à partir d'un système de navigation pédestre. La première étape décrit un modèle topologique 3D spécialement développé pour la localisation. Les éléments constitutifs d'un bâtiment, comme les corridors, les escaliers et les pièces, sont modélisés afin d'assurer une cohérence pour les besoins de la navigation. La construction du réseau s'appuie sur la théorie des graphes qui préconise l'usage de f

Context of indoor navigation The objective of this research is to define and to implement a dedicated data model for indoor applications. Based on this specific model, route guidance and navigation algorithms can be integrated in order to develop applications with particular requirements. 2. Geodata modelling and algorithms for navigation In this paper, we present the development and the implementation of algorithms to access map databases by a user equipped with a pedestrian navigation system. The first

Personal navigation has grown rapidly with the introduction of ubiquitous computing and the new generation of smart phones. Appropriate localisation is nowadays a central element for many applications and mobile services. However the proper estimation of t ...

In view of the operational validation of EGNOS, some early tests are being performed with the EGNOS System Test Bed (ESTB). This prototype has been broadcasting an EGNOS-like signal since early 2000. The performance of ESTB is reduced compared to the full deployed EGNOS, but it gives the opportunity to test EGNOS equipment and gain experience. Eurocontrol, skyguide and the Swiss Federal Institute of Technology in Lausanne (EPFL) are active in data collection and analysis in order to study the signal-in-spac

The Geodetic Engineering Laboratory (TOPO) at the Swiss Federal Institute of Technology (EPFL) has introduced e- learning into its undergraduate topography course. The Centre for Research and Support of Training and its Technologies (CRAFT) has introduced the Moodle Learning Management System (LMS) to facilitate this. TOPO has developed and introduced online exercises as an alternative to its traditional classroom-based teaching methods. The motivation behind this is to move from teaching and learning in a

Today, Intelligent Transportation Systems (ITS) and Personal Mobility (PM) applications are one of the most promising markets for GNSS. However, the high influence of operational and environmental conditions on GNSS performance in the road sector has led to various standardization initiatives that despite their substantial contribution many scientific issues are still open and a unified certification process is missing. SaPPART (Satellite Positioning Performance Assessment for Road Transport, TU1302) is a C

This chapter presents the various positioning technologies used in pedestrian navigation. The basic principles as well as the main advantages and disadvantages of positioning methods in the context of urban mobility are discussed. The development of navigation systems has led to the establishment of digital navigation maps containing the network of different traffic routes. In the future, pedestrian navigation technology, both attractive and feared, will be accepted if legal and commercial regulations of us

Navigation is usually associated with marine and aviation domains. Except for some lighthouses for orientation or landmarks near the coast, navigation instruments are essential because routes are virtual. Therefore, current position of ships and aircrafts must be drawn on the map. Land navigation is generally bound to the road infrastructure. Car navigation systems have been introduced to replace the use of road maps in order to assist the driver in the choise of the correct way...

Global Navigation Satellite Systems (GNSS) has become a kind of positioning standard due to the high penetration rate of this technology on mass market ITS applications. However, this positioning technique remains a real challenge for very demanding services. This paper reports on a practical and methodological approach for the evaluation of the GNSS positioning and attitude of vehicles in real life conditions. Test scenarios have been set up with several positioning sensors mounted on a vehicle for the col

Ces dernières années, les méthodes de localisation ont pris un essor important dans de nombreuses activités humaines. Connaître sa position a toujours été une préoccupation de l'homme qui a développé, au fil du temps, les moyens nécessaires pour s'orienter et se déplacer au bon endroit.

Lorsque l'on évoque la navigation pédestre, passablement d'idées préconçues influencées par le monde cinématographiques viennent à l'esprit. Connaître sa position, et principalement celle des autres, en tout temps et en tous lieux, a influencé bon nombre de croyances ainsi que le syndrome du "grand frère qui veille sur vous - Big brother is watching you", malheureusement pas toujours à des fins protectrices. La réalité est pourtant d'une très grande complexité...

Traffic problems have mainly resulted from an increase in mobility over the last decades involving an increase in traffic congestion and degradation of environmental conditions. The employment of new systems - namely, Intelligent Transport Systems (ITS) is ...

The Institute of Photogrammetry has developed a peripheral system for the automatic derivation of digital terrain models for the analytical plotter Kern DSR 15; this project is carried out in close collaboration with Leica AG. The principal component of the system is a parallel processor based on Transputer technology. The correlation process itself runs off-line on the Transputer system according to the Multi-Templet-Matching procedure. In a second phase, the results of the image correlation are smoothed d

The development of road telematics requires the management of continuously growing road databases. Mobile mapping systems can acquire this information, while offering an unbeatable productivity with the combination of navigation and videogrammetry tools. However, such technically advanced devices only go together with significant investments in staff and hardware. The Geodetic Engineering laboratory of the Swiss Federal Institute of Technology in Lausanne continues developing user-friendly and low-cost proc

This presentation describes the main ITS (Intelligent Trasnportion Systems) services and their requirements in positioning. Different types of navigation systems are presented with a focus on satellite-based systems and the potential of Galileo with value added services.

Positioning, tracking and communication (PTC) systems are the basic components of cooperative systems, and it is their development in recent years that has in turn made possible the idea of cooperative systems. The ongoing developments of GNSS (Global Navigation Satellite System), of new short range communication systems either between vehicles (V2V) or between the vehicles and the roadside (V2I), lead to new possibilities which have to be taken into account in traffic management. These technologies a prima

When Massive Open Online Courses became a hot topic in Europe. The Ecole Polytechnique Fédérale de Lausanne (EPFL) decided to take the challenge and launched an internal call for proposals. At the Geodetic Engineering Lab, we saw a possibility to use contact hours for exercises and fieldwork, rather than telling stories and showing diagrams. External students were considered, but the main purpose was to modernise the first year course "Fundamentals of Geomatics" for approximately 250 civil and environmental
