on 26th of February 2011 the Russian Space Agency launched the first satellite of the new GLONASS-K generation. With this new satellite GLONASS is able to transmit CDMA navigations signals in addition to the traditional FDMA signal which is normally used for positioning. It is the first GLONASS signal, which based on CDMA technique. This new CDMA signal is transmitted within the L3 frequency band with a centre frequency of 1202.025 MHz and is used for tests. The Institute of Communications and Navigation was able to receive the GLONASS-K CDMA signal on 5th of May 2011 using a measurement setup in the ground station Raisting. The first significant result is, that the received signal shows the expected band width and time behaviour but is remarkable stronger as other GNSS (about.5dB stronger as comparable GPS signals). Additional analysis has to be done because deformations in the envelope of the signal are visible. It is planed that the Russian navigation system transmits additional CDMA signals on the frequency bands L1, L2 and later on L5 if the tests with the first CDMA signal on the launched GLONASSS-L satellite are successfully. The switch over to CDMA for GLONASS allows interoperability to systems like GPS or Galileo.
