GPS L2
1227.60 MHz
Secondary GPS carrier frequency. Originally restricted to the military P(Y) code, it now also carries the civil L2C signal broadcast by modernized GPS satellites. Used with L1 for dual-frequency civil positioning and for characterizing ionospheric delay; a secondary target for wideband GNSS jamming.
