Abstract:	The challenging schedule of the Galileo development requires starting design of user and reference receivers as early as possible. LABEN (a Finmeccanica Company) is leading a consortium that is in charge of a pre-development study for the Galileo Ground Mission Segment Reference Receiver, under ESA contract. The main objective of the pre-development study is to define the receiver specifications and to define the preliminary architecture of the receiver including RF/IF, digital and software sections. The pre-development activity will be completed with analysis and simulation of the critical design issues in order to consolidate the specifications and architectural choices. The receiver specification and architecture will form the basis of subsequent detailed design cycles. The receiver design is supported by the development of a modular SW simulator, which allows investigation and trade-off between different design schemes and algorithms for BOC signals acquisition and tracking and for Navigation & Time solutions. The paper provides an overall description of the receiver design and focuses on the main choices and critical characteristics for the processing of the Galileo signals. It presents an overview of the simulation SW and discusses some preliminary performance results in terms of signal acquisition and tracking.
