Galileo FOC Procurement ‘Short List’ Announced

Eleven contenders have been selected to build elements of the Galileo system — the so-called fully operational capability (FOC) infrastructure.
In a September 19 announcement, the European Commission (EC) and the European Space Agency (ESA) said they had chosen the candidates out of 21 applicants in the initial phase of the procurement procedure.

Following an invitation issued July 1, interested parties submitted a “Request to participate.” Candidates were short-listed on the basis of pre-defined selection and exclusion criteria.

Logica’s GSA Contract for Galileo Security

The European GNSS Supervisory Authority has awarded Logica, a UK-based IT and business services company, a framework contract for the provision of security for the Galileo program.

The framework contract will run for up to four years and will enable the GSA to procure specialist support for the analysis and definition of security aspects related to Galileo with a shortened procurement cycle. It was awarded after a competitive tender and positions Logica as the preferred supplier for Galileo security, according to the company.

GIOVE-B Signal Observations Confirm MBOC’s Multipath Advantage

Standard deviation of code multipath for Galileo signals transmitted by GIOVE-B. The two thicker lines show the L1BC modulations: BOC(1,1), light green, and CBOC (dark green).

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

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.
