The AALECS team has taken part of the ION GNSS+ 2014 and Navitec 2014, both are very important international conferences about the GNSS navigation where the latests improvements and enhancements in this field are presented. AALECS team several publications explaining the work done during the year 2014 about the Galileo Commercial Service design, development and testing and the Early Proof-of-Concept execution.
In “Preparing for the Galileo Commercial Service – Proof of Concept and Demonstrator Development” by I.Rodríguez et al; the CS Demonstrator (architecture and operational modes) and its role in the roadmap to the Galileo CS is presented; and the different authentication solutions that will be defined and implemented are adressed. The paper also describes the planned test campaign, which has allowed the testing of the Galileo CS functionalities and the evaluation of its potential performance in simulated and real environments, including the broadcast of the CS signals through the Galileo satellites and CS signal reception in a receiver. Finally, the strategy to offer to potential CS Providers a platform where to test and validate new services that they may offer to the GNSS user community are presented.
“Galileo Commercial Service from the Early Definition to the Early Proof-Of-Concept” by D.Calle et al; presents the context of the Galileo CS and the different activities and results obtained during the Galileo CS Definition phase. Secondly it introduces the CS Early Proof-OfConcept and shows the first results obtained using the real Galileo E6 signals during the EPOC-SIS-Tests.
In “Design Drivers, Solutions and Robustness Assessment of Navigation Message Authentication for the Galileo Open Service” by I.Fernández et al; it is presented and characterized one Navigation Message Authentication (NMA) solution for the Galileo E1B Open Service signal.
“Galileo Commercial Service Demonstrator – Signal in Space Proof-of-Concept” by E. Carbonell et al; presents the context of the Galileo CS Demonstrator, and focus on description of the architecture and operation of the CS Demonstrator Early Proof-Of-Concept. In addition, it is also the aim of the paper to describe in detail the Signal-In-Space (SIS) test strategy of the EPOC and present the final results and achievements of the test campaign.
