M. Schubert studied Electrical Engineering and Infor- mation Technology at the University of Karlsruhe, Ger- many. Since 2007 he is member of the scientific staff at the Institute of Communications and Navigation, German Aerospace Center (DLR). During his studies, he was in- volved in a research project concerning inertial measure- ment unit (IMU) calibration at the Delft University of Tech- nology, Delft, The Netherlands, and he developed a simu- lation software for a robust powerline communication sys- tem at the Massachussetts Institute of Technology, Cam- bridge, USA. Since 2007, F. M. Schubert is participating in the European Space Agency’s Networking/Partnering Ini- tiative (NPI) together with DLR and the University of Aal- borg working towards his Ph.D. He is working on topics such as radio channel modeling for satellite navigation and the influences of harsh multipath environments on satellite navigation receiver performance. A. Lehner studied Mechatronics at the Johannes Ke- pler University in Linz. Since 2001, he is a research scien- tist at the German Aerospace Center. In 2007 he received a Ph.D. in Electrical Engineering from the University of Erlangen-Nuremberg, Germany. His research and project work focuses on the analysis of multipath and interference effects in satellite navigation systems and the design of inter-vehicle communication systems. A. Steingass received his Electrical Engineering di- ploma in 1997 from the University of Ulm, Germany. Since then he has been a research scientist at the German Aero- space Center. He has been involved in several projects in the area of satellite navigation and location-dependent mo- bile services. In 2002 he received his doctoral degree from the University of Essen. P. Robertson received a Ph.D. from the University of the Federal Armed Forces, Munich, in 1995. He is cur- rently with DLR, where his research interests are naviga- tion, sensor based context aware systems, signal process- ing, and novel systems and services in various mobile and ubiquitous computing contexts. B. H. Fleury received the diploma in Electrical En- gineering and Mathematics in 1978 and 1990 respectively, and the doctoral degree in Electrical Engineering in 1990 from the Swiss Federal Institute of Technology Zurich (ETHZ), Switzerland. Since 1997 B. H. Fleury has been with the Depart- ment of Electronic Systems, Aalborg University, Denmark, as a Professor in Communication Theory. He is the Head of the Section Navigation and Communications, one of the eight labs of this department. Since April 2006 he has also been affiliated as a Key Researcher with Forschungs- zentrum Telekommunikation Wien (FTW), Austria. B. H. Fleury’s current areas of research include stochastic mod- elling and estimation of the radio channel, especially for multiple-input multiple-output (MIMO) applications and in fast time-varying environments, and iterative information processing with focus on efficient, feasible advanced re- ceiver architectures. R. Prieto-Cerdeira received his Telecommunications Engineering degree in 2002 from the University of Vigo, Spain, and followed postgraduate studies on Space Science and Radioastronomy in Chalmers University of Technol- ogy, Gothenburg, Sweden. Since 2004, he has been with the European Space Agency (ESA/ESTEC) in the Wave Interaction and Propagation Section where he is respon- sible of the activities related to radiowave propagation in the ionosphere and local environment for Global Naviga- tion Satellite Systems (GNSS) such as Galileo and EGNOS projects, satellite mobile communications, and remote sens- ing and planetary radio science projects.
