In this paper we present a framework for the representation of location information from various sources, such as satellite navigation systems, wireless positioning technologies, beacons, indoor navigation systems, human input, etc. These sources all operate at various degrees of accuracy and often suffer from independent errors. Their output, in terms of(More)

BIOGRAPHY Christophe Macabiau graduated as an electronics engineer in 1992 from ENAC (Ecole Nationale de l'Aviation Civile) in Toulouse, France. Since 1994, he has been working on the application of satellite navigation techniques to civil aviation. He received his Ph.D. in 1997 and has been in charge of the signal processing lab of the ENAC since 2000.(More)
Vehicles in motion are exposed to mechanical vibrations, resulting from various sources, such as the engine, transmission, wheels, the track and many more. Vibrations in vehicles are often undesired, but these vibrations contain navigation and vehicle information. In addition to state-of-the-art techniques for the computation of spatial vehicle movements(More)
SUMMARY This paper summarizes the main results of an early investigation on desirable signal structures for the European &Galileo' civil satellite navigation system. Stemming from the requirements for increased accuracy, reduced time-to-"rst-"x and integrity information provision, the report describes the logical steps and the related numerical results(More)
A novel MIMO (multiple input multiple output) satellite channel model that allows the generation of associated channel impulse response (CIR) time series depending on the movement profile of a land mobile terminal is presented in this paper. Based on high precise wideband measurements in L-band the model reproduces the correlated shadowing and multipath(More)
