Russia sent one more navigation satellite to the GLONASS cluster in space on Monday. The Soyuz-2.1b launch vehicle blasted off from the Plesetsk space center in Arkhangelsk region at 12:26 Moscow time (0826 GMT), and it would position the Glonass-M satellite in the designated orbit of about 20,000 km above the Earth.
Three Glonass-M satellites were launched on a Proton-M rocket from Baikonur, Kazakhstan earlier last month. This cluster now has 30 satellites, 23 of them are working, two under maintenance, two on standby and three to be put into service. This system requires 24 operational and two to three reserve satellites in orbit to ensure global coverage.
