SIGMA · Study of Innovative GNSS Multiconstellation Algorithms

This project aims to develop innovative positioning and integrity algorithms for demanding applications. SIGMA will investigate and implement different positioning techniques based on satellite navigation, mainly focusing on the integration of signals from two different satellites systems: GPS and Galileo. Galileo, the most important technological project initiated by Europe, is expected to be ready by 2013. SIGMA will benefit from the opportunities that a multiconstellation environment offers for the evolution of high accuracy and high-integrity demanding applications. The different expertises of the participants will be exploited through joint research teams creating the ideal environment for innovation. Pildo Labs will provide is expertise on GNSS application for aviation and the requirements for this kind of systems in terms of navigation performance. Septentrio will provide its expertise on optimising GNSS algorithms for use in commercial products with limitation on memory and processor capabilities, and defining the requirements for high-accuracy demanding applications. TU Delft will support both companies with its expertise on precise positioning and advanced RAIM techniques, while CTAE will support the project through deep analysis on multipath and interference effects.
