On September 27, the first two Galileo Full Operational Capability (FOC) satellites were handed over from the European Space Agency’s Space Operations Centre (ESOC) in Darmstadt, Germany, to the Galileo Control Centre, Oberpfaffenhofen, which will care for them pending a final decision on their use. The satellites, launched on August 22, are in excellent health and working normally. However, a launcher problem left... read more

Galileo FOC Anomaly Traced to Design Ambiguity, Says Inquiry Board

October 8, 2014By

The root cause of the anomaly that sent two Galileo satellites into the wrong orbit is a shortcoming in the system thermal analysis performed during stage design, and not an operator error during stage assembly, according to findings by an independent inquiry board. The Independent Inquiry Board was formed to analyze the causes of the anomaly occurring during the orbital injection of satellites... read more

Improper Fuel Line Installation Led to Incorrect Galileo Orbit

October 6, 2014By

The cause of two Galileo satellites being released into the wrong orbit August 22 can be traced to improper installation of a hydrazine fuel line, according to Space News and the GalileoGNSS blog. The hydrazine fuel line was installed too close to a supercold helium line on the Fregat upper stage, which caused the hydrazine to freeze long enough to upset the Fregat stage’s orientation... read more

Summer — and the Living Ain’t Easy

September 29, 2014By

Summer 2014 will be one that the €6.3 billion (US$8.2 billion) Galileo GNSS programme will need to chalk down to experience and hope to move on from. At the time of my last EAGER column, we were starting to get a hint that one of the four in-orbit Galileo IOV satellites was not functioning. We now know that it has... read more

Galileo’s Two Giant Steps Back

September 24, 2014By

Galileo’s first two full-operational capability (FOC) satellites have been in a safe state since August 28, under control from the European Space Agency’s (ESA’s) center in Darmstadt, Germany, despite having been released on August 22 into lower and elliptical orbits instead of the expected circular orbits. ESA continues investigating the possible exploitation of the out-of-position satellites to maximum advantage, despite... read more

The fifth and sixth Galileo satellites have been in a safe state since August 28, under control from ESA’s center in Darmstadt, Germany, despite having been released on August 22 into lower and elliptical orbits instead of the expected circular orbits. The European Space Agency has released two diagrams showing the orbits. ESA said that the potential of exploiting the... read more

Galileo Conspiracy Theory

PLUS: Flying for GPS Book Review
Do you know any conspiracy theorists? You know, those folks who I am sure are well meaning, but see a conspiracy behind every event? Think Mel Gibson in the great 1997 movie with the very imaginative title Conspiracy Theory. Well, the conspiracy theorists have been coming out of the woods following the Galileo launch fiasco, and they are blaming both the Russians and European Space Agency for allowing the Russians the capability to effectively render useless what should have been the first two operational Galileo PNT satellites. read more

Galileo Provides Update on FOC Anomaly, GLONASS a No Show

September 10, 2014By

Experts representing the Galileo Program provided a frank and open update on how it is addressing the problem of the first two full operational capability (FOC) satellites being delivered to the wrong orbit. The presentation was part of the panel discussion “Status of GPS, GLONASS, Galileo, BeiDou, and QZSS” at ION GNSS+ Wednesday morning. No one from Rocosmos attended to... read more
