GIOVE-B Signal Observations Confirm MBOC's Multipath Advantage

Initial results from observations of the Galileo GIOVE-B satellite conducted by researchers at the European Space Agency (ESA) and Septentrio Satellite Navigation indicate that the multiplex binary offset carrier (MBOC) modulation outperforms the BOC(1,1) modulation on the L1 (data + pilot channels) frequency in mitigating the effects of multipath or reflected signals.

First GIOVE-A/B Double Difference Observed

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.

ESA Opens Galileo Procurement: Let the Games Begin!

Today (July 1), the European Commission (EC) — with the support of the European Space Agency (ESA) — launched the procurement process for Galileo with an invitation to companies to submit requests for participation as prime contractors for six work packages (WPs) valued at €2.145 billion (US$3.39 billion).

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.

Air Force Tanker Controversy May Influence Galileo Competition

A U.S. Government Accountability Office (GAO) assessment that the U.S. Air Force made “significant errors” in awarding a $35 billion contract for refueling tankers to a consortium including the European Aeronautic Defense and Space Company (EADS) may affect the prospects of foreign participation in development of the Galileo system.

GNSS Album: Images and Spectral Signatures of the New GNSS Signals

Until now, civilian global satellite navigation systems (GNSS) receivers have had essentially only one signal, the GPS L1 C/A-code, reliably available for navigation. However, in the coming years, many more operational GNSS signals, systems, and frequencies will become available to civilian users.

SIDEREUS: Linking EU, Asia SMEs with Galileo Focus

A European initiative is seeking to link small and medium-sized enterprises (SMEs) in Asia and Europe through a series of one-on-one encounters between businesses operating in the aerospace and information and communication technology (ICT) sectors, with a special focus on Galileo-based satellite navigation applications.

Galileo and the Earth’s Gravity Field

Most readers will certainly associate the new European global navigation satellite system Galileo with the name of the famous Italian physicist, astronomer and philosopher Galileo Galilei. Undoubtedly the name of the program has been well chosen if we consider the achievements of the historic Galileo in astronomy and physics alone.
