First GIOVE-A/B Double Difference Observed

GIOVE-A/B Double Difference Ambiguity Measurements, TU Delft

Researchers at Delft University of Technology (TU Delft), the Netherlands, succeeded this week in simultaneously tracking the GIOVE-A and GIOVE-B L1 Open Service signals in space, producing the first reported computation of a double-difference carrier phase integer ambiguity resolution on the first two experimental Galileo satellites in orbit.

EC Issues ITT for a GNSS Advisor

EC Issues ITT for a GNSS Advisor

The European Commission (EC) Directorate-General for Energy and Transport (DG-TREN) has issued an invitation to tender (ITT) for an advisor on the European GNSS program.

With a one-year term renewable up to three times, the contract will be designed to provide a pool of experts and organizations for review and counsel on administrative, financial, strategic and technical matters. The services are outlined in two “workpackages,” one for a fixed set of activities and the other for variable services performed according to specific work orders.

Galileo’s GIOVE -B Spacecraft Transmits Signals

Europe’s second Galileo In-Orbit Validation Element (GIOVE-B) satellite began transmitting navigation signals on May 7, including the common GPS-Galileo civil signal MBOC (multiplexed binary offset carrier).

Built under a cooperation between the European Space Agency (ESA) and European Union (EU), GIOVE-B was launched April 27 from the Baikonur cosmodrome in Kazakhstan. The MBOC signal design will be used by the future GPS L1C broadcasts as well as the Galileo Open Service in accordance with an agreement drawn up in July 2007 between the EU and the United States.

Locked to an on-board passive hydrogen maser clock, the GIOVE-B signals will help improve positioning accuracy in challenging environments with multipath and interference as well as better penetration for indoor navigation.

Galileo’s Drama: Different Set, Additional Actors, a New Play for Europe’s GNSS?

Passage of a new regulation on Galileo sets the stage for the next phase of the €3.4-billion satellite navigation system’s development under a public procurement but leaves many details to be worked out among the key players: the European Commission (EC), the European Council, the European Parliament, and the European Space Agency (ESA).

Meeting in Strasbourg, France, the parliament adopted the measure on April 22 with 607 votes in favor, 36 votes against, and 8 abstentions.

“Things are looking up, finally, for the European GNSS programs,” Paul Verhoef, head of the Galileo unit in the EC’s Directorate-General for Transport and Energy, told an April 23 plenary session of the European Navigation Conference 2008 in Toulouse, France.

May 16: Deadline Extended for abstracts for NAVITEC 2008 – ESA workshop on satellite navigation user equipment technologies

The European Space Agency has extended until May 16 the deadline for paper abstracts for oral and poster presentations for NAVITEC 2008, ESA’s fourth workshop on satellite navigation user equipment technologies.

This year’s theme is "GNSS User Technologies in the Sensor Fusion Era." Galileo receiver technologies and experimentation are a special focus of this year’s event.

The workshop will take place from December 10-12 at the European Space and Technology Centre in Noordwijk, The Netherlands.

Galileo’s GIOVE-B Satellite Opens New Era of GNSS Signals

A new generation of GNSS signals will become available soon as Europe’s second Galileo In-Orbit Validation Element satellite (GIOVE-B) reached orbit, following successful launch on Sunday (April 27) from the Baikonur cosmodrome in Kazakhstan.

Riding a Soyuz/Fregat launcher, the 500-kilogram (1,100-pound) spacecraft lifted off at 12:16 a.m. Central European Summer Time (CEST). The Fregat upper stage performed a series of maneuvers to reach a circular orbit at an altitude of about 23,200 kilometers inclined at 56 degrees to the equator. The two solar panels that generate electricity to power the spacecraft deployed correctly and were fully operational by 5:28 CEST.

The European space Agency (ESA) operational schedule called for Galileo signals at three L-band frequencies to begin transmitting within seven to eight hours after reaching orbit, according to Giuseppe Viriglio, ESA’s director of telecommunications and navigation.

ESA Creates Galileo Directorate, Appoints Oosterlinck

René Oosterlinck, ESA Galileo Director

In an April 15 meeting, the Council of the European Space Agency (ESA) has created a Galileo Directorate to accommodate the agency’s newly enhanced role in Europe’s GNSS program.

Acting on recommendations of ESA’s Director General Jean-Jacques Dordain, the council agreed to bring back René Oosterlinck, former head of the Navigation Department, to serve as the director of the Galileo program and navigation-related activities (D/GAL) through the end of 2010.
