Septentrio’s AsteRx3 Tracks First GLONASS CDMA Signal on L3

It is the first of two GLONASS-K1 satellites and the first ever GLONASS satellite capable of transmitting a CDMA ranging signal. The GLONASS system has traditionally employed FDMA, in contrast to CDMA employed by all the other GNSS systems. However, CDMA signals in multiple frequency bands will be broadcast by future GLONASS satellites. The GLONASS-K1 satellites mark a first step in this direction. On April 7, the GLONASS Information-Analytical Center announced that experimental navigation signals of the first GLONASS-K1 satellite would be activated. Septentrio’s AsteRx3 receiver is now successfully tracking the new L3 CDMA signal broadcast by the satellite and also its L1 and L2 signals (L1-C/A, L1P, L2-C/A and L2P). Read More
