ESA Will Attempt to Improve Orbits of Errant Galileo Satellites

The European Space Agency (ESA) announced plans today (November 10, 2014) to implement a series of maneuvers to reposition one of two Galileo full operational capability (FOC) satellites left in the wrong orbit this summer, as a prelude to its health being confirmed.
 
The aim is to raise the lowest point of the satellite’s orbit — its perigee — to reduce the radiation exposure from the Van Allen radiation belts surrounding Earth, as well as to put it into a more useful orbit for navigation purposes.

Airbus GNSS Engineers Win Top ESNC 2014 Prize

Airbus GNSS Engineers Win Top ESNC 2014 Prize

The European Satellite Navigation Competition (ESNC) has gone Big Time.

Unlike past years, when product designers and engineers from small- and medium-sized enterprises (SME) have walked away with the top prize, this year’s overall winner was Airbus Defence & Space (Airbus DS GmbH), a division of the Airbus Group (formerly EADS). Headquartered in France and generating annual revenues of €14 billion, Airbus DS was established last year by the merger of the parent company’s Airbus Military, Astrium, and Cassidian units.

New Home (or Not) for Galileo in European Commission

New Home (or Not) for Galileo in European Commission

The European Parliament voted yesterday (October 22, 2014) to accept President-elect Jean-Claude Juncker’s “last-chance” leadership for the European Commission (EC).

But the 11th-hour reshuffling of posts appears to leave Galileo without a clear-cut leader, at least at the political level — even as the Commission and its European Space Agency (ESA) partner have decided to give up the prospect of a December launch of two satellites.

GNSS+: PNT Heads for the Great Indoors

A confluence of technology, policy, and applications is turning indoor venues into the next big frontier for positioning and navigation.

Recent market studies have heralded the prospects for positioning, navigation, and tracking inside buildings where GNSS signals are often attenuated or blocked entirely. Many products and conceptual designs combine the indoor technologies with GNSS to provide “ubiquitous” positioning.

ICAO, RTCA Seek New Protections for GNSS Aviation Receivers

ICAO, RTCA Seek New Protections for GNSS Aviation Receivers

GPS pseudolite used in experiment at University of New South Wales Satellite Navigation and Positioning Lab

International aviation officials have asked U.S. experts to consider updating standards for GNSS aviation receivers to improve their ability to withstand interference from repeaters, pseudolites, and jammers.  

Repeaters — generally used to extend navigation signals inside buildings where they would otherwise be blocked — rebroadcast GNSS satellite signals and therefore operate in the same frequency band. Although useful within a building,  care must be taken to confined the repeater’s signal lest it confuse other receivers operating nearby.

European Commission GSA Sign Agreement on Galileo Service Provision

GSA Executive Director Carlo des Dorides

The European GNSS Agency (GSA) and the European Commission (EC) have concluded an agreement that delegates a range of exploitation tasks for Galileo to the GSA, providing a framework and budget for the development of services and operations through 2021.

The signing of the Galileo Exploitation Delegation Agreement serves as an initial step towards the full Galileo Exploitation Phase.

Arianespace Inquiry Identifies Source of Galileo Launch Anomaly; Next Attempt Could Come in December

Arianespace Inquiry Identifies Source of Galileo Launch Anomaly; Next Attempt Could Come in December

In a report issued Tuesday (October 7, 2014), an Independent Inquiry Board formed to analyze the cause of the August 22 launch anomaly that placed two Galileo into the wrong orbits has concluded that frozen fuel lines caused a misfiring of attitude control thrusters on the launcher’s Fregat module.

According to the report, the problem can be remedied on the rockets in time for another launch in December, much sooner than some observers had speculated.

A Learning Experience

A Learning Experience

My favorite bumper sticker this month: “Oh, no! Not another learning experience!”

After 20 years of putting together a European GNSS program, disappointment over the skewed launch of the first fully operational Galileo satellites is palpable and widely felt. For end users, it is uniformly bad news, and no system provider that sincerely wants to achieve interoperability and robustness in a system of GNSS systems can relish the European program’s current difficulties.
