GALILEO Augmentations for Precise Positioning Applications

Ray Jones, Ian Casewell, Gethin Morgan-Owen and Alan Whitelaw

Abstract:	The paper addresses aspects of the design of GALILEO augmentation systems and the resultant services that may be delivered to future users of precise positioning. Following some brief contextual information relating to the GALILEO project, its core system and Local Elements (augmentations), the paper identifies key applications and discusses the performance and business needs of the main user communities. The service delivery business models appropriate to these user communities are then described. The paper then addresses the GALILEO signals in space together with those anticipated to be available from modernised GPS that are relevant to commercial precise positioning in the 2008-2010 time frame. Two potential GALILEO Local Element architectures are then described. Assessment of the performances achievable by these architectures is then discussed. The work to be carried out under the remainder of this task is then described. Finally, interim conclusions resulting from this on-going study are presented. This paper is based upon work conducted within EC and ESA funded Galileo studies. The views expressed are the opinions of the authors and do not reflect EC/ESA policy.
