Septentrio’s AsteRx3 receivers are successfully tracking the GLONASS CDMA L3 signal transmitted by the first GLONASS-K1 satellite. This satellite was launched on February 26. It carries a payload capable of transmitting a CDMA signal in the L3 band, with a center frequency of 1202.025 MHz, in addition to the standard L1/L2 GLONASS FDMA signals. 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
