An Early Gift from — and for — Galileo

December 19, 2014By

They said it wasn’t possible — well to be frank, I said it wasn’t possible – but one of the two “misplaced” Galileo satellites, plucky Doresa, has delivered an early Christmas present to the European GNSS community by providing a first fix on Tuesday, December 9. The signal was received at the European Space Agency’s (ESA’s) technical centre in Noordwijk,... read more

GNSS System Mandates Would Violate International Trade Agreements

November 26, 2014By
global-deal

A U.S. government representative stated at an international satnav forum that mandating use of specific GNSS services for applications such as air-traffic control, freight shipments, emergency calling, and road tolling could violate the terms of World Trade Organization (WTO) agreements that many nations, including all six GNSS providers, have signed. Regional mandates already exist for Glonass in Russia and Beidou... read more

Galileo: A Constellation of One?

October 29, 2014By

Matters sit not well with Galileo, the European GNSS. Only one of six currently orbiting satellites can be said to be truly and fully operational. With these troubles augmented by persistent uncertainties regarding the fitness of Soyuz rockets, despite a recent inquiry panel that identified a root cause of the August launch failure, the European Commission has nixed an upcoming... 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

Slung Low, Sweet Satellites: Galileo Anomaly Update

August 28, 2014By and
Galileo_satellites_inside_launch_fairing_O

The wording is terse, the intent clear. “Following the failure on Friday August 22nd to inject Galileo satellites 5 and 6 into the correct orbit, the European Commission has requested Arianespace and the European Space Agency (ESA) to provide full details of the incident, together with a schedule and an action plan to rectify the problem.” This is the only... read more

A Long Look at Advanced Multisensor Navigation and Positioning

July 30, 2014By

A modern-day fable related by Steven Covey tells of a civil engineer leading a crew engaged in building a road through a dense jungle. Each day the engineer’s adept management, the crew’s motivation and energy, and the high-tech equipment at their disposal pushed the new road well beyond scheduled targets. Midway through the allotted month, the engineer decided to climb... 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
