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.

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.

Russia launched a Proton-M rocket carrying three GLONASS-M satellites from the Baikonur space center at November 4 after a 24-hour delay due to technical reasons, a spokesman for the Federal Space Agency Roscosmos said.
This was first launch of a Proton-M rocket with GLONASS satellites from Baikonur since a failed attempt last December. That led to the dismissal of several top officials in the space agency and industry and the appointment of Vladimir Popovkin to head the space agency.
Next-generation car navigation may well require the ability to identify the lane in which a vehicle is operating on a motorway. This could support advanced driver assistance in general as well as the observation and study of driver behavior and traffic flow. Such road vehicle applications call for sub-meter positioning accuracy, often in real-time — all this preferably at low-cost.
