Galileo's GIOVE-B Broadcasting New MBOC Signal

摘要

Following its April 27 launch, GIOVE-B, the second Galileo satellite, began transmitting navigation data on May 7, the European Space Agency (ESA) reported. GIOVE-B is now transmitting the Galileo L1 signal using a specific optimized waveform, multiplexed binary offset carrier (MBOC), the signal that will be interoperable with the L1C signal to be used in future Block III GPS satellites, in accordance with the July 2007 agreement between the European Union and the United States. GIOVE-B signals were locked on-board by the satellite's passive hydrogen maser clock, the newest and most accurate clock in space.
