Squeeze at the Launchpad for Galileo

March 31, 2014By

With the first two full-operational-capability (FOC) Galileo satellites successfully through their thermal-vacuum tests, the program’s next hurdle is securing a firm launch date in June aboard a Europeanized Russian Soyuz rocket, operated from Europe’s spaceport on the northeast coast of South America. It will not be a walk in the park. Competing with the two Galileo FOC satellites for the... read more

The System: Galileo Accomplishes In-Orbit Validation

March 1, 2014By

Galileo Accomplishes In-Orbit Validation Nucleus of Four Now Operational: It “Works, and Works Well” The European Space Agency (ESA) announced fulfillment of the in-orbit validation (IOV) of Galileo on February 10. IOV was achieved with four satellites, the minimum number needed to perform navigation fixes. “IOV was required to demonstrate that the future performance that we want to meet when... read more

Directions 2014: Galileo IOV Passes with Flying Colors

December 1, 2013By

Following the second Galileo launch in October 2012, leading to four operational satellites in orbit, a progressive chain of events has taken place in 2013 encompassing all Galileo Services, starting from the first position fix on March 12 (Figure 1), when navigation message continuous broadcast began. read more

Time to Hit Warp Speed, Galileo

April 23, 2013By

Report from ENC: Constellation Needs 22 Satellites in Three Years Launch, deploy, and operate “22 satellites in less than 3 years.” That’s two satellites every three months, leading to a four-at-once launch in 2014. And that’s the challenge that Europe and the European Space Agency (ESA) now face. This pointed call to action during the opening plenary of the European... 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

PLAN Group Tracks Galileo Satellites for Positioning in Canada

March 15, 2013By

by James T. Curran, Mark Petovello, and Gérard Lachapelle Within a day of their initial activation over central Europe on March 12, Galileo satellites were visible over North America. The PLAN Group of the University of Calgary was successful in capturing and processing the signals from these satellites as they emerged. Galileo PRN 11, 12, and 19 were found and... read more
