Transmissions from Galileo Satellite IOV-3 Have Begun

December 3, 2012By
Javier Benedicto, ESA's Galileo Project Manager, looks on as Europe's own satellite navigation system performs its historic first position fix of longitude, latitude and altitude. The position fix took place at the Navigation Laboratory at ESA’s technical heart ESTEC, in Noordwijk, the Netherlands on the morning of 12 March, with an accuracy between 10 and 15 metres – expected taking into account the limited infrastructure deployed so far. Horizontal accuracy reached as high as 6 m. The left-side screen shows the position fix while the right side screen shows the position of the four Galileo satellites and their current signal coverage.

According to a report from the Technische Universitaet Muenchen, transmissions of the L1/E1 signal from the recently launched Galileo satellite IOV-3 (FM-3) started at about 13:55:20 GPS Time December 1. Transmissions from IOV-3 of the E5 signal began December 2. By December 4, all three Galileo bands, including E6, were being broadcast, according to the European Space Agency (ESA).

Galileo Satellites Cleared for Launch

October 9, 2012By
Soyuz VS03, the third Soyuz flight from Europe’s Spaceport in French Guiana, was transferred to the launch zone on October 8. The vehicle was rolled out horizontally on its erector from the preparation building to the launch zone and then raised into the vertical position.

Europe’s next two Galileo satellites have received technical clearance for their launch this Friday. They are currently resting in place atop their Soyuz launcher. Yesterday saw the three-stage Soyuz ST-B launcher moved horizontally to the launch pad on the 600-meter long railway. It was then lifted into the vertical position to await the attachment of the Upper Composite — the... read more
