GLONASS has “preliminary approval” to transmit CDMA GLONASS signals at L1, L5

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.

Proton launch failure raises questions about timeline for completing GLONASS constellation

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 Labors to Bring Latest GLONASS Satellites On Line

The Russian Space Forces are continuing efforts to bring the final two GLONASS spacecraft launched December 25 into operation.

One of the trio of satellites (SV798 in slot 19) went on the air in late January. Reports from the Russian news agency RIA Novosti, quoting Russian space officials, subsequently attributed the delay to frozen fuel lines in the satellites.
