Abstract:	The European Tripartite Group, (ESA – EC – EUROCONTROL) has implemented, via the EGNOS project, the European contribution to the first generation of Global Navigation Satellite System (GNSS-1). The European Space Agency (ESA) has been in charge of the system design, development and qualification of an Advanced Operational Capability (AOC) of the EGNOS system (also known as EGNOS V1). In summer 2005, EGNOS has reached two major program milestones through the formal technical qualification process (known as ORR, Operational Readiness Review) and the start of its initial operations. These two events mark a successful completion of more than 8 years of intensive work by ESA and European industry. In parallel to the start of EGNOS operations, EGNOS is planning a modernization plan to cope with GPS modernization, service extension, standard evolutions and the anticipation of some future Galileo missions. In this context, the availability of free bandwidth enables systems like EGNOS to broadcast additional communication messages. These messages could be, the broadcast of • Warnings or instructions on the occurrence of natural disasters, calamities, dangers for the safety of life within areas with poor telecommunication infrastructure • Search and Rescue Return Link Messages. • Warnings or instructions on limitations in the use of SBAS for specific applications (e.g. aviation) • Other uses. We refer to these, in general, as the Communication Function of EGNOS. Of these, this paper will focus mainly on the first two, with two concrete proposals: the ESA ALIVE Concept, (Alert interface via EGNOS) and the SAR Return Link. The authors consider the ESA ALIVE and the SAR return link proposals as meaningful and viable concepts, which may be implemented in a reasonable short time frame, contributing to save lives in the event of disasters.
