Surrey Satellite Technology Ltd. (SSTL) completed the Giove-B in-orbit testing. The second experimental satellite of the Galileo constellation is operational and it's working well. In particular, the maser clock seems operative: "Additional test results also indicate that the hydrogen maser atomic clock onboard GIOVE-B is working correctly, according to SSTL.". GPS World reports that SSTL tested again Giove-A. The first experimental satellite is still in good conditions..
