Technical Status of the Galileo System Development

Abstract : The development of the Galileo System continues under the partnership of the European Commission and the European Space Agency. ESA is charged with the development of the elements of the "Global Component," which will be comprised of the complete constellation of satellites together with the ground segment. The ESA development will culminate in the establishment of an In Orbit Validation (IOV) milestone, which will contain a minimum number of each element of the Full Operational Configuration (FOC). An overview of the Galileo services and requirements is provided. We briefly outline the architecture of the Galileo Global Component. We also introduce the overall development approach and risk mitigation activities such as GSTB-V1/V2 and GIOVE-A/B/M. The interoperability aspects (i.e. GGTO) are highlighted as well. The present master working schedule is presented.
