What is a "Glonass L2"? The Most Authoritative Explanation.

What is L2 band GLONASS?

GLONASS L2 Band. The transmitted navigation signal is, as also in L1, a bipolar phase-shift key (BPSK) waveform with similar clock rates as in the L1 band. The L2 signal is modulated by the Modulo-2 addition of the PR ranging code and the auxiliary meander sequence.

What is GLONASS-K1?

GLONASS-K1 transmit a CDMA signal on a new L3 frequency (1202.025 MHz), and GLONASS-K2, in addition, will feature CDMA signals on the L1 and L2 frequencies. Like GPS and the other GNSSs, the GLONASS signals also contain navigation messages providing satellite orbit, clock and other information.

How does GLONASS work?

All GLONASS satellites transmit the same code as their standard-precision signal; however each transmits on a different frequency using a 15-channel frequency division multiple access (FDMA) technique spanning either side from 1602.0 MHz, known as the L1 band.

What is L1 signal in GLONASS?

Table 1: GLONASS L1 signal technical characteristics. It is important to note that unlike for the case of GPS and Galileo in the previous chapters, the frequencies do not have to be multiplied by the factor 1.023. CDMA Open Service Navigation Signal in L1 frequency band is called L1OC.
