Abstract:	Unlike GNSS-1, there is no agreed blueprint for GNSS-2. The latter is defined as “a seamless satellite global navigation system which meets ALL the needs of the civilian community in a cost effective way”. This definition has led to an extensive research programme, led by the European Commission to investigate several possible options. Most notable among these are proposals based on MEO, LEO and IGSO satellite configurations. The various alternative proposals are based on distinct satellite configurations, with different payloads, ground segments, signal structures and measurement systems. They all enjoy a number of distinct advantages, and suffer from a number of drawbacks. The purpose of the GNSS SAGE Project is to bring together a number of leading European scientists, from both universities and industry, to study these and other GNSS-2 options. The project will concentrate on the technical merits of all possible options, and assess them, bearing in mind multi-modal user requirements, manufacture, launch and maintenance costs, and the global dimension of a European satellite navigation system.
