Galileo’s GIOVE-B to Launch April 14
The first Galileo experimental satellite, which marked its second anniversary in space on December 28, may soon have company.
Designated the Galileo In-Orbit Validation Element–A (GIOVE-A) satellite, the spacecraft has been broadcasting a variety of signals since January 2006, using on-board rubidium clocks for time-tagging signal transmissions. Now, GIOVE-B — the larger second experimental satellite, which will carry one hydrogen maser and two rubidium clocks, is nearing readiness for transfer to the Russian Baikonur launch facility in Kazakhstan.
