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.

Russia would almost certainly continue broadcasting FDMA signals on existing frequencies.

Russia Labors to Bring Latest GLONASS Satellites On Line
