Obiettivo del progetto (Objective)

'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.'

Introduzione (Teaser)

Satellites circling the Earth provide important information critical to positioning and guidance systems. Novel improved algorithms developed with EU support will enhance accuracy and certainty to meet demanding requirements.

Descrizione progetto (Article)

From aircraft and shipping applications to finding your home on images of the Earth, global positioning has become ubiquitous. EU-funded scientists launched the project 'Study of innovative GNSS multiconstellation algorithms' (SIGMA) to develop superior positioning and integrity for demanding applications.

They integrated signals from the two satellite systems, the American Global Positioning System (GPS) and the European satellite GALILEO, as a testbed.

Using a simulation platform developed specifically for the project to test multiconstellation algorithms, the researchers developed and evaluated three different routes to enhanced performance.

Improved integrity (certainty of location) was addressed with receiver autonomous integrity monitoring. Enhanced accuracy (precision of location) exploited precise point positioning. Finally, the team also evaluated innovative techniques to mitigate multipath and interference disturbances that compromise the signal quality at the receiver. The target applications were navigating an aircraft approach (certainty over precision) as well as surveying or machine control where accuracy is critical.

SIGMA technology should be welcomed by numerous fields demanding integrity of position or accuracy currently not available with conventional satellite positioning algorithms. Leading the pack will have important impact on the competitive position of the EU and its economy.
