Arianespace, ESA Sign Contract for New Galileo Launches

August 22, 2014By
The contract for Arianespace’s three Ariane 5 launches to orbit a total of 12 Galileo FOC satellites was signed at the Guiana Space Center by Chairman and CEO Stéphane Israël (seated, at left) and Didier Faivre, ESA director of the Galileo Program and Navigation-related Activities. Joining them were ESA Director General Jean-Jacques Dordain and Daniel Calleja Crespo, director general for Enterprise and Industry, European Commission.

Arianespace and the European Space Agency (ESA), acting on behalf of the European Commission, have signed a contract for three launch services with Ariane 5 ES to step up deployment of Galileo satellites. With this new launch contract and thanks to the performance of Ariane 5 ES, a total of 12 Galileo FOC (Full Operational Capability) satellites will be launched... read more

Retired GIOVE-A Helps SSTL Demo High-Altitude GPS Fix

November 30, 2012By
Galileo's GIOVE-A retired in June 2012

An experimental GPS receiver, built by Surrey Satellite Technology Limited (SSTL), has successfully achieved a GPS position fix at 23,300 kilometers altitude – the first position fix above the GPS constellation on a civilian satellite. The SGR-GEO receiver is collecting data that could help SSTL to develop a receiver to navigate spacecraft in geostationary orbit (GEO) or even in deep... read more

By Richard B. Langley, Simon Banville, and Peter Steigenberger. For a brief period, and for a few hours on certain days, signals from the first four orbiting Galileo satellites could be received by state-of-the-art multi-frequency, multi-constellation GNSS receivers. Although not intended for actual positioning tests, the satellites did provide a first opportunity to assess the prototype Galileo signals in the... read more
