Last week, the SatNav blog informed us three GLONASS-M satellites have been successfully launched by Russia.
From the entry: “If recent indications from the Russian government are anything to go by this will represent the first launch of many leading to the restoration of a 30 satellite constellation by 2011. Another launch of 3 satellites is planned for 2008, most likely on Christmas Day.“
The same blog informs us GIOVE-B, GALILEO’s second test satellite, has been knocked offline by “space radiation”. From the BBC article: “This region of space is known to have a high intensity of fast moving particles that can disrupt spacecraft electronics. But the conditions are reasonably well understood, and engineers will want to know why Giove-B experienced the glitch. Giove-A is unaffected.“
