A photo of the NavSAS group (December 2011)On December 12, 2011, one of the two Galileo in-orbit validation (IOV) satellites launched on October 21 — the Galileo- ProtoFlight Model (PFM) spacecraft — started transmitting its payload signal on the E1 band over Europe.
That same day NavSAS researchers were able to acquire and track the E1 signal (Galileo Code Number 11) beginning at 14:46:15 CET. Two days later, on December 14, the E5 signal became available as well.

Baska, Krk Island beach
This annual seminar on the Croatian Adriatic aims at GNSS experts and
covers the risks and vulnerabilities of the global navigation satellite
systems and efforts to improve accuracy and reliability.
The sixth GNSS Vulnerabilities and Solutions Conference will take place at Baska on the resort island of Krk in Croatia from May 21 to May 24, 2012.

The European Space Agency (ESA) has reported its first successful reception of triple-frequency signals from a Galileo in-orbit validation (IOV) spacecraft.
The weekend of December 17 all Galileo signals were activated simultaneously for the first time across the European GNSS system’s three spectral bands, known as E1 (1559–1592 MHz), E5 (1164–1215 MHz), and E6 (1.215–1.300 MHz). The accompanying graphic displays the signals spectral profile.

The PRN 11E5b autocorrelation function as monitored by TAS-I receiver (x axis represents chip spacing y, time in seconds).[Updated December 14, 2011] Today (December 12, 2011), the first of two Galileo IOV satellites launched October 21 began transmitting its payload signals.
Researchers at several European organizations have reported initial acquisition and tracking results of the E1 signals from the Galileo-ProtoFlight Model (PFM) satellite (previously incorrectly identified as Flight Model-2), also identified by its pseudorandom noise code (PRN 11).

Paul Weissenberg of the European Commission’s Enterprise and Industry directorateAfter years of arduous political navigation filled with delays and disappointments, Europe’s GNSS programs appear to have found firmer ground as it heads into a crucial deployment phase.
Today (November 30, 2011), the European Commission (EC) proposed a €7 billion (US$9.41 billion) allocation for Galileo and EGNOS in the European Union’s next budget cycle (2014–2020) and delegation of the programs “exploitation” to the European GNSS Agency (GSA) and the systems’ deployment, to the European Space Agency (ESA).

Many technologies are created before their best applications are even thought about. This leads to a business phenomenon known as “technology push” in contrast to “consumer pull.” The True3D Volumetric HUD technology did not share this path.

Europe’s first two Galileo satellites have reached their final operating orbits, opening the way for activating and testing their navigation payloads.
Marking the formal end of their launch and early operations phase (LEOP), on November 3, control of the satellites was passed from the CNES French space agency center in Toulouse to the Galileo Control Center (GCC) in Oberpfaffenhofen, Germany.
