Study into applicability of Galileo in Location Services (LCS)
Based on the March 2003 GALILEO system definition, in the present document, as proposed in [1]:
• the potential benefits of using Galileo (alone or combined with GPS) on service performance: in particular the availability improvements for in urban/indoor environment are highlighted.
• the expected complexity differential between 3GPP mobiles utilizing A-GPS and those that might utilize a combination of A-GPS plus “Assisted GALILEO” is described.
• the changes that might be needed to 3GPP standards to support “assisted Galileo” in addition or in combination with the currently specified assisted GPS are identified
• from the 3GPP community point of view, the desirable characteristics of GALILEO that would minimize the impact to 3GPP mobiles when introducing the extension of A-GPS techniques to GALILEO are proposed.
These informations will allow 3GPP to decide whether or not to initialise 3GPP standard changes to introduce GALILEO. The final 3GPP standard modifications should be reassessed against the final GALILEO definition.
