System Definition

A series of System Studies are carried out to identify the best strategy for all technical activities performed within the context of AGILE.

The objectives of the System definition here are to specify and design the overall technical solution (overall architecture and network design) in compliance with the project objectives and to trade-off and justify the main technical choices.

The User Terminal Definition task specifies and designs the overall technical solution for a terminal (or set of terminals) representative of mass-consumer production models; and to trade-off and justify the main technical choices.

The Local Element Definition performs the overall system design and specification of the local elements needed to enable the overall LBS solution/architecture. This provides a definition of the technological building blocks required by a commercial LBS service at the network level, with particular focus on the hybridisation of GNSS (and in particular EGNOS/Galileo) with core commercial wireless communications systems; the interoperability of ground and space-based geo-location (through the integration of A-GNSS technology with Cell-ID, EOTD and other forms of network-based positioning in commercial operation); the simulation of the Galileo signal; the preliminary definition of advanced forms of local accuracy enhancements; the preliminary concepts for a commercially-viable integrity service; the identification of non-technical constraints (legal, standards etc).  The interface with the EGNOS Data Server (EDAS) will also be considered during the AGILE architecture definition.

The Enhanced Technology task demonstrates Galileo improvements on location coverage and studies new emerging technologies that will complement the Galileo-based location solution for deep indoor location.  Different levels of simulation, using in-house tools, are conducted giving special consideration to signal propagation in representative urban canyons and light-indoor environments, and location enhancements enabled by the combination of network assistance and WLAN-/pseudolite-based location techniques.
