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

UDPATE: After a one-day postponement, The fifth and sixth Galileo satellites were successfully launched and deployed. UPDATE: Arianespace has decided to postpone the launch of Soyuz flight VS09 carrying Europe’s fifth and sixth Galileo satellites. This is due to unfavorable weather conditions over the Guiana Space Centre. Another launch date will be decided depending on the evolution of the weather conditions... read more

Galileo’s Troubled E20 Satellite Is Alive

August 7, 2014By

The troubled Galileo E20 satellite restarted E1 signal transmission Wednesday evening, August 6. Galileo E20, also known as GSAT0104, the fourth in-orbit validation (IOV) satellite, has been set “unavailable until further notice” according to the European GNSS Service Centre because of a sudden, unexpected loss of power on May 27. Based on a selected set of IGS MGEX stations and all CONGO stations, the... read more

GalileoStatus-O

In an update to our July 2 story (recapped below), correspondent Peter de Selding wrote in Space News on July 3 that the trouble aboard the fourth in-orbit (IOV) Galileo satellite arose from a sudden, unexpected loss of power. The power outage flashed on May 27, shutting down the satellite’s E1 signal. The signal “re-established itself almost immediately. But as... read more

Occupy Media Space Now EGNOS and Galileo Mission

June 29, 2014By

By Peter de Selding The message to the recent European Space Solutions conference in Prague was simple enough: EGNOS is here, so let’s use it; Galileo is almost here, so let’s promote it. Neither task is straightforward. Take the European Geostationary Navigation Overlay Service (EGNOS), the European piece of a near-global network of terminals on geostationary satellites linked to networks... read more

Results are being processed from the first Galileo maritime trials outside of mainland Europe. The long-range, high-latitude testing spanned the North Sea, following the same historical sailing route that Viking dragon-ships used 1200 years ago. Ancient manuscripts record Viking navigators relied on “sunstones” to find their way — archaeologists believe these may have been polarizing crystals to pinpoint the Sun... read more

Scientists in Hanoi, Vietnam, send word that on March 27 the four Galileo in-orbit validation satellites were visible at the same time in the sky over that Southeast Asian country for nearly two hours (from 2:15 to 4:00 GMT) while transmitting a valid navigation message. The research team of the NAVIS Centre at Hanoi University of Science and Technology (HUST)... read more
