Hi Randy

All GPS SVs emit the L2 1227.6 MHz frequency which carries only the P code
used for the precise positioning service (PPS) and the L1 1575.42 MHz C/A
(coarse acquisition) signal which is the standard positioning service (SPS).

The L2 frequency is the same for the NAVSTAR GPS SVs and the Russian GLObal
NAvigation Satellite System (GLONASS).
