First Galileo Commercial Service demonstration with encrypted signals Publicado el: 24/07/2014, Última actualización: 22/06/2015
Between July 15th and July 25th, Galileo signals (E6-B and E6-C) have been under test, as reported in a recent NAGU (Notice Advisory to Galileo Users). The main purpose of the tests was to verify the Galileo Commercial Service signal encryption functionalities.
The test execution has gone according to plans.
During this 10-day period, receivers at Tres Cantos, Spain and Poing, Germany have shown the successful tracking and data demodulation of spreading code encrypted signals from Galileo satellites.
The signals also incorporated authenticated navigation data generated outside of the Galileo system. Both features are essential for future Galileo high accuracy and authentication services, some of which may become commercial.
These tests have been made possible thanks to a collective effort by the EPOC (Early Proof-of-Concept) team of the AALECS (Authentic and Accurate Location Experimentation with the Commercial Service) consortium together with the European Commission, the European GNSS Agency (GSA), the European Space Agency (ESA) and Spaceopal, the Galileo operator.
The European Commission launched the AALECS project in January 2014. The project was awarded to a consortium led by GMV which includes CGI, Qascom, IFEN, Veripos and KU Leuven.
The AALECS project is building a platform to connect to the GNSS Service Centre in Madrid and transmit real time 'commercial service' data through the Galileo satellites. This platform is planned to become operational by 2015 and will demonstrate the real performance of future high accuracy and authentication services of Galileo.
As a previous step, the project participants GMV and IFEN have developed an Early Proof-Of-Concept platform aimed at testing external data transmission through offline means.
The project will last for around two and a half years.
