Russia’s space forces had an easier time of it bringing the latest set of GLONASS-M satellites on line within just over a month after launch.
As of December 6, the GLONASS constellation had 15 operational satellites, two of which are not broadcasting signals during maintenance. The next launch of three modernized GLONASS space vehicles is scheduled for December 25.

Russia successfully launched three modernized GLONASS (GLONASS-M) satellites from the Baikonur Cosmodrome in Kazakhstan on October 26, a day later than planned due to a Kazakh national holiday. The Proton-K rocket, equipped with a Block DM upper stage and carrying three Uragan-M (GLONASS-M No. 18, 19, 20) satellites, lifted off at 11:35 Moscow time.

Russia’s GLONASS-MInvestigation into a Proton-M rocket failure in September, which appeared to threaten the schedule for continued rebuilding of the GLONASS constellation, has cleared the launcher and Baikonur facility for renewed activity, including a scheduled October 25 launch of three GLONASS-M satellites.

GLONASS has gotten “preliminary approval” to add code division multiple access (CDMA) signals to future satellites.
Since its initiation in the early 1980s, the Russian GNSS system has employed frequency division multiple access (FDMA) techniques in which the same code is used for the signals broadcast by the system, with individual spacecraft being distinguished from one another by a specific frequency allocation. Russia would almost certainly continue broadcasting FDMA signals on existing frequencies.

The September 6 crash of a Russian Proton-M rocket carrying a Japanese telecommunications satellite (JCSAT 11) has injected an element of uncertainty into plans for completing the GLONASS constellation.
Russia’s Baikonur cosmodrome automatically suspended all Proton rocket flights, pending an investigation, after the failure of the rocket, which crashed in the steppes of Kazakhstan just over two minutes after lift-off. Russia rents the space facility from Kazakhstan, a former republic in the USSR.

Russia is showing ever-stronger signs of a serious intention of not merely restoring its GNSS system, GLONASS, but of turning it into a true dual-use system with a presence in civil and commercial markets.
